Ordinary sealing tape is any company, personal life indispensable supplies, because of its technical content is not high, many domestic manufacturers, so the quality of the product on the market uneven. And our domestic tape industry still remain in the technical content of very low stage, the state has not yet a perfect standard for the tape. Many consumers understand the tape is cheap, feel better viscosity, in fact, this is wrong. Buy tape do not map cheap, a sub-price goods, cheap tape must be made from the raw materials on the issue, today's Pacific packaging to teach you how to identify the quality of tape is good or bad!
1. The composition of the tape:
Sealing tape is BOPP biaxially oriented polypropylene film on the basis of high-pressure corona after a rough surface coated with glue, and then sub-machine into a small volume is our daily use of the tape, so the first tape Strength depends on the BOPP film is good or bad and thickness, the average thickness of the film between 28 microns and 30 microns, but because of some of the recycled material BOPP film strength is not enough, so only thicker film thickness, It feels very thick, but the intensity is very poor, very short shelf life will appear obvious aging. Tape with color is for easy marking and masking purposes, not the color of the film, but the color of the glue.
Ordinary sealing tape glue is acrylic tincture glue, also known as pressure-sensitive adhesive. Tincture is a kind of macromolecular active substance, the temperature has a certain impact on molecular activity. Glue tincture material directly affect the use of tape, many individuals think that sticky tape is good glue, in fact, this is wrong. Adhesive tape in the use of good or bad there are two standards, one is the initial sticky force, one is to maintain the force, the two are inversely proportional. Normal sealing tape The thickness of the glue is generally 22-28 microns, which is in line with the standard thickness.

2. Identification of tape:
In fact, we use the tape is not the purpose of sticky, but to sticky solid will not be separated. Now most of the poor quality of the tape in use, after a period of time (20 minutes to 1 hour) will appear disintegration of the situation, and can not be re-paste; followed by poor quality tape easily broken, the intensity is very low, mainly with the quality of the membrane , But also to avoid sharp objects to scratch the tape cross section, or no matter how good the tape will be broken. Some people think that the tape surface with bubbles and more tape is certainly not a good tape, it is not true, the tape has just passed into the finished product when there are bubbles, placed for some time after the basic bubble will be dispersed.
In addition, the regular production of tape paper tube thickness of 100 meters below the tape is 3 mm, 100 meters above the 4-5 mm, while small businesses for the blind consumer use thick paper tube, usually the thickness of 5-7 mm thickness , And thus relatively large in appearance, but the tape is very clear on the flesh of the more out. So when the choice of tape must see the width of the tape and the thickness of the tape.
In summary, we have been able to determine the tape from the appearance of the basic can determine the tape is good or bad, and then a good distinction between good and bad tape is the most important condition is not just feel feel viscosity, because the doped tape in the absence of volatile time The initial sticky force is very high, so use the tape to paste the object and then quickly opened to see the holding force, repeated paste several times and then touch, the obvious feeling of sticky decline. Dumped tape for glue when the general use of gasoline and acid to be dissolved, so the smell is very large.

The packing machine is suitable for the automatic packing and binding of various kinds of goods such as carton packing, paper packing and so on in food, medicine, hardware and other industries.

How to calculate the most accurate PP packing belt? Today Pacific packing belt for each customer to explain how to correctly price packing belt?

When many customers consult our Pacific packing belt, the first question is how much is your packing belt a roll? , although we should not only pay attention to the price of the packing belt when choosing the packing belt, but it is undeniable that the price is definitely an important factor to buy the packing belt. Now let's talk about how to calculate the price of the packing belt.

General packing belt factory price calculation is the price of each roll is equal to the price per kilogram multiplied by the weight of each roll. But Pacific packaging belt that different manufacturers are equipped with different raw materials, the cost varies greatly, but the use of packing belt is the unit of length rather than weight. Therefore, when you choose the packing belt products, in addition to the length of the packing belt, the proportion of the packing belt, the performance of the packing belt and other environmental protection, and the price. Our Pacific packing tape has introduced a new pricing method of packing tape, the price of packing tape per roll is equal to the price per meter multiplied by the length of each roll.

It's usually the length of the straps that we use, not the weight. The price of the packing belt is more reasonable in meters. Pacific packing belt to strive for every customer to save every penny, for greater profit.

PP packing belt how to store packing belt is the most commonly used packaging materials in industrial production, the vast majority of enterprises in order to produce the need to store spare packing belt. So we are in the storage of packaging belt is the most correct way, the following to Pacific packaging to explain to you:

First of all: plastic packing belt should be stored in the warehouse, to prevent the sun, rain; Stop touching with acid, alkali and oil agent, adhere to clean and dry, distance from the equipment 1m, the room temperature between -15℃~40℃.
Secondly: not the same type, not the same standard type, strength, the number of layers of plastic packaging belt connection (matching) together.

Finally: the packing belt should be placed in rolls without folding. If the storage time is too long, it should be turned quarterly.

Storage of Pacific bale is done as described above. Warehouse rigorous fireworks, packaging belt under the card board to prevent mildew, damp. Our company is to ensure that every product shipped to the customer company is intact, do the best supplier for customers.

The principle of PP packaging belt production line:

1. The main and auxiliary machine transmission of PP packing belt production line consists of speed regulating motor, reducer and shaft sleeve. The forming part is composed of screw barrel, head and mouth die. Raw materials are heated and extruded into the screw barrel through hopper to extrude the initial embryo.

2. The water tank of PP packing belt production line is used to cool the primary embryo of the main and auxiliary machine mouth mold. The temperature of the strip head is very high, so it should be cooled in water immediately. Because the isometric polypropylene is easy to generate the brew crystal structure under the condition of quenching, and the crystal molecular structure is relatively loose. Easy to stretch orientation, high quality products

3. The first traction of PP packaging belt production line consists of speed regulating motor, traction roller, reducer and chain drive. It is to transfer the shaped initial embryo to the oven.

4. The secondary heating of the oven under the PP packaging belt production line is easy to stretch; the main purpose of the stretching is to improve the longitudinal strength of the packaging belt and reduce the elongation. The three heating of the oven on the packaging belt production line eliminates the tensile stress, and the upper water tank can eliminate the thermal stress and then set the shape.

5. The drive of the embosser in PP packaging belt production line is that the speed regulating motor is driven by belt, chain and gear to the second traction, to the embossing, and then to the traction.

① The second traction will re stretch the second heated embryo through the pull bar, and then deliver it to the embossing roller;

② After stretching, the packing belt passes two pressure rollers with patterns and is pressed on the pattern. Its function is to increase friction in use, without slipping, and it is beautiful and generous from the appearance. The product surface is embossed by the embossing roller and then transported to the upper water tank or upper oven;

③ The packaging belt production line transmits the forming of the upper water tank to the belt winding machine through the third traction.

6. The drive of the winding machine in PP packaging belt production line is that the speed regulating motor is transmitted to the winding shaft and the travel rod respectively through belt drive and chain drive. It is a single product that takes the qualified product into a specified shape and quality.

Above is about the principle of PP packaging belt production line and everyone introduced here, to learn more PP packaging belt production line can call us for consultation.

The maintenance and lubrication of the packing machine should be carried out regularly. First, keep the packer dry. It should not be wet or put water on it.

Regular maintenance of the packer:

1. Remove the scraps or dirt from the packer once a week

2. Once a month, clean and lubricate the upper sliding plate mentioned in the previous section, the middle knife and the front top knife.

3. Add some lubricating oil to all (shaft, center) and bearing after the above two maintenance are done every three months.

4. Replenish the oil in the gearbox every two years.

5. It is necessary to note that several parts cannot be refuelled: a. the belt roller is sent and withdrawn. b. All belts. c. Slip and surrounding.

6. Do not add too much oil every time to avoid the micro switch failure due to oil immersion.

The progress of domestic packing belt industry has greatly promoted the development of food, daily chemical and other industries. In turn, the development of these industries has further stimulated the demand for the packing belt market, making the packing belt industry obtain huge market power. With the rapid growth of domestic packaging demand, packaging belt as a supporting material has a wide range of development prospects in various fields of national economic development.

But on the other hand, due to the serious homogenization of products in the packing belt market, large competition and low profits, with the progress of technology and the development of the market, customers' requirements for product quality and service are constantly improving, the competition among enterprises is becoming increasingly fierce, coupled with the great changes in the political, economic and social environment, the domestic PP packing belt industry has gradually become a completely competitive industry. In addition, the plastic industry is closer to the end consumers, and is a capital intensive and trade oriented industry, which is more sensitive to the economic environment.

In such a market background, the Pacific packing belt has the advantages of imported equipment, stable quality, reasonable price, the strongest pulling force and complete specifications, which are prominent in the packing belt market. However, we are not satisfied with this. Under the traditional marketing mode, we have contacted the e-commerce for a long time, because we know that good products also need more sales channels, in addition to the mouth of customers Besides spreading, we should also keep up with the trend. The Internet has the characteristics of transparency, openness and rapidity. It has a wider source of information and a faster spreading speed. Therefore, we must meet it with the same open mind, move forward with its pulse speed, and win more sales opportunities in e-commerce.

A lot of people in the purchase of packing belt will feel that the packing belt thick, better than the thin, this should be the most normal people's first sensory judgment, but the fact is not the case, packing belt manufacturers for you reveal such as identification of a packing belt is good or bad:

The quality of the packing belt is good or bad, depending on the purity of the polypropylene packing belt is not high, there are many kinds of packaging belt on the market: pure polypropylene, polypropylene

You pack

Add master stock, polypropylene plus recycled stock, polypropylene plus recycled stock and master stock. The packing belt produced by pure polypropylene is fully transparent, the packing ground produced by polypropylene plus master material is translucent, the packing belt produced by polypropylene plus recycled material is basically opaque, and the packing belt produced by polypropylene plus master material and recycled material is completely opaque. There is also a packaging belt produced by fully recycled material and calcium carbonate powder sandwich material. The packaging belt produced by completely recycled material is relatively soft. Only the surface of the belt of sandwich material is raw material, and the rest is calcium carbonate powder (lime powder). The quality of the packing belt completely depends on the purity of polypropylene, the higher the purity of polypropylene packing belt, the better the tension.

Joint mode of packing belt:

A) Hot melt lap type. It adopts heating methods such as electric heating welding, mechanical high frequency oscillation welding and ultrasonic welding. It is a way of bonding the plastic belt joint after the surface of the plastic belt is heated and melted, then the two melt surfaces of the belt end are lapped together and kept under a certain pressure for a certain period of time until the melting surface condenses. The joint mode is suitable for polypropylene plastic belt, because if the polypropylene plastic belt is mechanically fixed with iron buckle, its strength is only 50% of the base material, and the adhesive connection is not applicable.

B) Iron buckle type. This method is to use the one-way work of the ratchet of the tensioner to tensify the belt, and then place an iron buckle at the joint, and then make the iron buckle cover the two layers of belt with clamps, and the side teeth of the iron buckle are concave and convex tooth shape, and bite the belt will not cause its loosening. Iron buckle is usually made of galvanized iron sheet, the operation should be based on the strapping belt model to choose the appropriate specifications of iron buckle.

C) Ligation. This kind of joint is made of soft plastic rope, hemp rope and so on, and the joint is made into a slip knot. This joint mode is not only firm and beautiful, but also easy to untie.

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.

Several commonly used packing belts:

You pack

Steel straps

It is generally used to make very heavy loads into one piece of transport or to fix loads in train cars, trailers or ocean cargo vessels. It is rarely used for contracted loads that have sunk or shifted after lashing, but it can be used firmly to tie compressed loads and is often used for rigid loads.

Nylon packing tape

With high continuous tension, it is generally used for heavy goods and contractive loads that can withstand high initial tension. Its elongation and recovery rate are greater than those of polyester or polypropylene strapping. It is the most expensive plastic strapping.

Polypropylene packing tape

It is the cheapest strapping material and is generally used for strapping, bundling and sealing cartons for lighter loads. Polypropylene packing tape has high elongation and recovery rate, but not as good as other plastic packing tape in terms of sustained tension.

Polyester packing tape

Highest strength and continuous tension in plastic packing tape. Polyester packing tape is an excellent strapping material for rigid loads that require constant strapping tension during loading, unloading, transportation, and storage. It is commonly used in applications requiring high tensile strength, high sustained tension and elongation. In many cases, its performance is similar to that of a lightweight specification steel packing belt.

PP packing tape

This product is used with automatic packaging machine, suitable for newspaper, publishing house, book office, paper mill, general merchandise, food, post office, confectionery, wood shop and so on.
