Packing tape alias strapping tape. The packing belt (binding belt) is made of polyethylene, polypropylene resin as the main raw materials, and nylon and polyester as raw materials. It is made of extrusion unidirectional stretching. The plastic strapping belt has good elastic recovery, high strength, good water resistance, strong chemical resistance, light and soft, which can be used for strapping and machine strapping. Easy to use, low cost, can be made into red, white, blue, yellow, green, and other colors, according to the color of the bundle of different grades of goods, easy to distinguish the grade of goods, improve delivery efficiency. In addition to being used for corrugated carton sealing and strapping, it can also be used for strapping materials, fruits, etc. Polyester and nylon strapping belt has good tensile strength, while polyethylene and polypropylene strapping belt has low cost. The resilience of polypropylene is good. Different materials of strapping belt can be selected according to needs. According to the use method, the plastic strapping belt can be divided into two categories: machine belt (J type) and manual belt (S type).

Classification of packing belts

Packing tape is a widely used consumable packaging material. It can be classified in different ways:

1, from the production of PP material can be divided into core belt and solid core belt; 2, from the quality of the product can be divided into transparent A, transparent B, A, AB, B, BC and C grade; 3. From the machine used, it can be divided into hand playing belt, machine playing belt (also divided into full automata playing belt and semi-automata playing belt); 4, from the scope of use can be divided into packaging with packaging belt and arts and crafts belt; 5, there are other sub-printing word belt and not printing word belt and so on.

1: Bend the left end of the packing belt, insert the packing buckle, and then fold the left fixing rod into the packing belt for tightening.

2: Hold the packing belt in the right hand to bypass the packaging, bend the right end of the packing belt into the packing buckle, and fold the left fixing rod into the packing belt.

3: The left hand is fixed on the packing buckle, and the right hand is pressed on the right end of the packing belt to tighten the packing buckle.

4: Finally, cut off the packing belt with scissors.

The packing tape is made of a mixture of PP and PET plastics. The main production process: plastic granule melt -- pressure belt -- molding -- cooling -- winding -- packaging -- warehousing packaging belt system using polypropylene through heating, melting, stretching, cooling produced by the network structure of packaging materials, the basic parameters affecting the quality of packaging belt are tensile force, length, bending, elongation, etc. As long as tension and other parameters are the same, the longer the length, the lower the cost.

Ningbo Pacific Packaging Belt Co., Ltd. is a specialized packing belt unit, PP packing belt, packing belt manufacturers, there is a need to call us, I wish you a happy New Year, a happy New Year!

At the present stage, PP packaging with a production line is more and more packaging machinery and equipment companies to choose, its full automation technology operation mode and high efficiency of the operation system software, suffered a lot of people's five-star praise. As everyone knows, with the accumulation of working hours and maintenance is not timely, automatic packing belt production line equipment will suffer a certain level of damage and destruction. Especially the screw and barrel of the packing belt production line are more vulnerable to damage than other parts.

But because in the design, the service life of the cylinder is generally designed to be longer than the service life of the screw, so relative to the wear of the screw, the normal wear of the cylinder is not needed to repair. Therefore, for the screw damage of automatic packing belt production line, how should we actually operate and repair?

Please pay attention to the following three points in daily operation of the packing belt production line:

1. Before the PP packing belt production line starts up. First, check whether the equipment and packing belt are interspersed correctly; Second, check whether the power supply wire is damaged, and then check whether the moving parts are lubricated, * to see whether the packing belt production line is fixed and does not move.

2. The operator of PP packing belt production line needs to be clear about the operation process. The operator of the packing belt production line should have a basic understanding of the structure, working principle, operating procedure and adjustment method of the packing belt mechanical equipment. Before operation, the power should be turned on, the machinery of the packing belt should be preheated for a few minutes, and the length of the packing belt should be adjusted. Of course, it is also necessary to listen to the noise of the packing belt production line.

3. After the operation of PP packing belt machinery, remember to cut off the power supply, and turn off the switch, to prevent leakage phenomenon, leading to electric shock.

How to repair the wear and tear of PP packing belt production line?

1. If there is wear on the top surface of the screw thread of the packing belt production line, we generally use surfacing to repair the special anti-wear and anti-corrosion alloy method. First, the surface of the outer circle (top of the thread) of the worn packing belt production line screw is ground to a uniform size. The deep cutting depth is generally 1.7mm, and the aluminum alloy layer is welded to sufficient height by electric welding to ensure the minimum sufficient feed. Then cut the outer side of the screw and the external thread side, the screw diameter generally exceeds the new screw specifications, the purpose is to compensate for the damage of the barrel, maintenance of the initial axial gap design scheme, packaging with production line partial destruction can also be applied in this way.

2. In view of the production line of the packaging belt with chrome plating and damaged coating, the metal material spraying technology has been applied to the production and maintenance of the packaging belt at present.

3. In the case of abnormal damage of the package with part of the shell of the production line, such as serious scratches near the end, the waterproof casing can be inserted. Be sure to pay attention to the nominal diameter of the waterproof casing as far as possible, and be lined with the relative metal surface treatment or wear-resistant steel pipe lining.

If you encounter such problems, you can solve them according to the above methods.

The most common packing materials are PVC, PE, PP, PET, etc., so the plastic packing belt can be divided into PVC packing belt, PE packing belt, PP packing belt, PET packing belt, in which PP packing belt and PET packing belt is the most common packing binding raw materials.

The ingredients are different
Production process and material classification of packing tape

PP (polypropylene) :

Appearance: transparent color to not fully transparent, color and lustre fully transparent plastic film.

Flammability: Flammable in flames. Leave the flame to slowly blow out or reignite. When the flame is lit, the upper part is pale yellow and the lower part is dark blue. There is melting and dropping condition. You can smell the bacon.

PET: Appearance: Fully transparent.

Flammability: flammability, leaving the flame to ignite again. The flames were pale yellow, and the exhaust pipes were emitting black smoke. Slightly bulged, sometimes cracked, butadiene flavor.

Second, from its compressive strength, PP packing belt of compressive strength is 10-15kg/cubic mm, PET packing belt of compressive strength of 42-55kg/flat mm, about 2 times of PP belt. 95mm*0.55mm PET tape can replace 19mm* L. B 250m PP tape, the same compressive strength. We are very concerned about the compression strength and length of the packaging belt, in the same length of the situation, the compression strength of PET plastic steel belt is 2.7 times the PP packing belt, so from a point we tend to choose PET plastic steel belt.

Third, flexibility, PET plastic steel belt is hard, than PP packing belt soft, but its elongation is one sixth of PP belt, packing belt manufacturers can maintain tension for a long time.

Fourth: from the point of view of its application site, PET plastic steel belt can replace the steel chain binding hanging objects, packing belt manufacturers can be widely used in steel, aluminum, chemical fiber, metal material can factory and other manufacturing industries. PP packing belt suitable for binding several KG to hundreds of kilograms of paper boxes or wooden box packing light blocks, can cooperate with each other automatic baler, semi-automatic baler, manual waste paper baler application.

Fifth, from the price level, PET plastic steel belt project investment is high, the cost is higher than PP packing belt. But PET plastic steel belt is not easy to rust, can be used repeatedly, from a long time, PET plastic steel belt cost-effective.

The packing belt is able to be reused many times, but it will be stained with a lot of dirt, which must be cleaned, so how to clean it properly? The following packing belt manufacturers for everyone to introduce in detail.

Actually not difficult, people can apply special drift lotion and toluene to carry out the washing, bleaching lotion price is low, it is recommended that applications floating lotion, but in the case of cleaning must pay attention to fire safety, evaporation poisoning, this have to do a good job in the natural ventilation, in addition, the above pattern can also be washed away.

What is the temperature resistance of the packing buckle?

Plastic packaging buttons: among 30 degrees - 70 degrees, heat, torrential rain, the transformation of dry, wet, no fading, mildew, embrittlement, brittle condition, such as general plastic baling press buttons are more suitable for temperature tolerance, because it can be resistant to high temperature of 100 degrees, so is a thriving packaging deduction, it not only tonal and diverse styles, complete with low price have relativity.

Tin packing buckle: generally can withstand 180 degrees of high temperature, not easy to deform and not easy to air oxidation.

The cause of this abnormal situation will be the insufficient thickness of the packing belt, which will also mean that the fusion time is not long, resulting in problems in the quality of the combination, and then the rupture. It will also be a part of the friction and fusion of the refrigeration time is too short, resulting in the combination of packaging belt is not strong, and then fracture. This must be applied to the appropriate specifications of the packaging belt manufacturers, according to the need to reduce its fusion time, so that it can be combined more firmly. In the case of production and manufacturing, we must make relative provisions and consider the characteristics of goods.

People in the case of the purchase should choose the quality of goods, so that it can give full play to the effect of the actual effect, to prevent some problems in the whole process of application, and people in the application of the case should also pay attention to the actual operating standards.

As one of the key equipment of polymer production and processing, the screw of plastic packing belt machine is widely used in polymer production and processing industry, and will be widely used in other industries. Labeling plastic packaging machine screw work performance in the key performance parameters are: screw diameter, screw length to diameter ratio, speed ratio of the screw is category, drag the main screw motor output power, machinery and equipment production, the heating output power of the cylinder, and according to the section number, the equipment management center of height to width ratio and size, etc., the main parameters is the key to the considerations and plastic packaging machine according to the design is plastic packaging machine first need to clear the performance parameters of the screw.

Optimal design of screw of plastic packing belt machine
According to the whole process of the transformation of the polymer in the three physical conditions of the screw of the unlined paper aluminum foil tape machine, and the working standards of each position of the screw, the screw of the plastic packing tape machine is generally divided into feeding section, melting section and metrological verification section. Because the geometrical structure of the screw is relatively complex, it is impossible to create a mathematical analysis model that can fully reflect the optimal design of the screw of the plastic packing machine. Even if we can create an ideal mathematical analysis model for the optimization design of the screw of plastic packaging belt machine, it is also very difficult to find out because of the numerous hazard elements and the many independent variables of the design scheme. Therefore, it is more practical to carry out the optimization design according to the action segment model of the screw.

The basic theory and method of screw optimization design of plastic packing machine

At present, the common optimization design methods of plastic packing machine screw include: analytical method, graphic method and computer simulation method. On the basis of the status of the extrusion process to create a physical model, based on the physical model to create mathematical analysis model, selection of Pro/E, ANSYS, Polyflow, such as mobile phone software Matlab to write process optimization design program, the program flow type electronic computer and according to the changes to optimize the overall goals of the assignment to carry out the optimization calculation, according to the results of the optimization of electronic computer output for parsing and certification, calculate the main parameters for optimizing the design of plastic packing machine.

The mathematical analysis model of the analytical form depends on the understanding of the working condition and the basic theory of the component to a great extent, besides the overall objective of the predetermined optimization. A schematic design can be expressed by the scalar values of a set of major parameters. Among them, the single main parameters that must be selected are called design scheme variables. Because the main parameters such as screw diameter, length-diameter ratio, external screw rising Angle and screw groove depth are related to the bearing capacity of the screw, production, driving force consumption, extrusion quality, and the performance of the screw machine, it is generally selected as the independent variable of the design scheme. The characteristics of optimal design of waterborne kraft paper tape machine screw are: design scheme independent variables; Multi-objective optimization design coexists with single-objective optimization design. Multidimensional and discrete systems of mathematical analysis models; Various dimensions coexist in the independent variables of the design scheme.

Optimal design of screw of single plastic packing belt machine

Tian PuJian from single plastic packaging machine screw extrusion process, basic theory, extrusion screw structure and main parameter of screw geometry melting performance, specifically consider screw melt quality specification, performance and to optimize the overall objectives, in polypropylene (PP)/natural bamboo powder as an example, the geometry of screw main parameters optimization. It is concluded that the special screw of WPC is more beneficial to the transportation of WPC melt than the general screw of plastic, and it can prevent a series of problems caused by the increase of WPC melt viscosity. The dimensions of the elements harmful to the working pressure field in the verification section of raw material melting measurement are successively as follows: the deep depth of the screw groove, the rising Angle of the external thread and the total width of the screw edge. If the deep depth of the screw groove is enlarged and the rising Angle of the external screw thread is reduced, the necessary energy consumption of the metering verification section can be reasonably reduced. The larger the depth of the screw groove, the smaller the lifting Angle of the external thread, the smaller the forward friction resistance of the melt, and the lower the kinetic energy consumed by the transportation of the melt in the metering verification section. With the increase of the total width of the screw edge, the kinetic energy consumed by the melt transportation in the measurement verification section has a trend of increase, but the trend of increase is relatively slow. If the total width of the screw is increased too much, the driving force cost on the screw will also be increased, and there will be a risk of partial overtemperature. The total width of the screw should be controlled in a certain suitable category. The use of Pro/E analysis system, finally identified the most suitable plastic packaging belt machine screw elements, and then exceed the purpose of improving productivity.

Today we Ningbo Pacific Packaging Belt Co., Ltd. to bring you a packaging belt procurement knowledge. We are the industrial production of PP packing belt, baler manufacturers.

The packaging belt industry has experienced the development of more than 30 years, the quality of the packaging belt on the market is uneven, the price from dozens of yuan to hundreds of yuan. In the procurement process, enterprises often only pay attention to the ton price, but ignore the actual length of each ton of packing belt. This deformity of the concept has also affected a part of the packing belt manufacturers, the market appeared sandwich packing belt, ton bag packing belt, raw material packing belt and other cheap and thick belt.

But the sandwich packing belt, ton bag packing belt, recycled material packing belt has a very low breaking strength, poor bonding strength, which affects the packaging quality of products. So, how do we distinguish the quality of the packing belt when we purchase the packing belt?

How to distinguish "new belt" from "plastic belt"

A brand new belt is made of 100% raw plastic material, which is the most efficient, but also the most expensive. The plastic tape is also made of 100% plastic, but is made entirely or partially of recycled plastic. So how do you tell if the straps are made of brand new material?

By the look. The packaging belt made of new materials is more beautiful, its material is transparent, and the color and lustre are uniform. For example, we can put a piece of written paper on the desk and put a piece of fresh material tape on top of the paper, and then we can see the words underneath the tape clearly, whereas the tape made of recycled material does not have this effect.

Next, distinguish from the feel. The packing belt made of new material has good rebound force, good hardness and thickness. We can compare the packing belt made of 100% new material with the packing belt mixed with recycled material. By stretching it in the opposite direction with our fingers, we can find that the packing belt made of 100% new material has a strong restoring force, while the packing belt made of recycled material is not hard enough, so the restoring force is not so good.

Again, one of the best ways to distinguish by experiment is by fire. The packing belt made of 100% new material will not have pungent smell when burned. The residual ash is crystal. The tape containing the recycled material will have an unpleasant pungent smell when burned, and the ash will contain other substances, such as lime.

Finally, welcome to consult us Ningbo Pacific Packaging Tape Co., Ltd. PP packing tape, baler, tape, film and other products. As a professional manufacturer, we will answer all kinds of questions about packaging for you.
