The price of polypropylene is rising recently, and the probability of increasing the balance between supply and demand in the middle and late period is very large, so it may increase the inventory in the future. The project investment plastic packing belt machine/plastic packing belt machinery and equipment production plastic packing belt can be taken into account the opening. In addition, the upstream and downstream costs continue to reduce, international crude oil prices, propylene prices continued to reduce for several days, bad news poly propylene, high prices are estimated to be unable to be maintained. Sichuan Yazhijiang Plastic Products Factory with you to master the details.

Inventory is still slightly low, after the potential is expected to improve

Polypropylene prices continue to go up, plastic packaging machine opportunity

Slightly lower inventory and tighter inventory is one of the key logics of today's double head sales market. According to the latest news and data information, the inventory has decreased significantly, and the inventory of trading companies has increased to a certain extent again. However, due to the cooling of temperature and the working pressure of transporting resources, the reliability of primary supply of energy and chemical industry in Northwest China is still uncertain. Requirements level, although the main performance of the middle and lower reaches of today's requirements are obvious to all, but with the temperature turning cold, the traditional requirements of the peak season just began to come, the middle and lower reaches of the social development of the stock digestion and absorption of work capacity just began to make the sales market worry, after the potential PP inventory will be further improved.

Futures prices will go down

PE is the immediate raw materials for PP manufacturing, from July to October data information, propylene prices parallel to pull up 2000 yuan/ton, but if the requirements of the downstream can not relay race, the probability of price decline is quite large.

With the release of the production capacity under construction in November and the acceleration of the repair of the supply side generated by the restart of maintenance equipment, the supply of the whole social development will continue to rise, and there is a great chance that PP will shrink and decline.

Continuous innovation is the driving force of the development trend of a manufacturing industry, but independent innovation is also a "trick". The rapid development of intelligent technology in the light industry, the intelligent operation scale of the agricultural industry chain has grown, and where should the technological innovation of plastic packaging machinery enterprises come from? It can only integrate into the sales market, constantly upgrade the current production line, increase the whole industrial chain, develop commodities, cooperate with each other in food manufacturing, food industry, food packaging materials and food safety testing and other stages, and keep improving itself. In particular, the key point is that independent innovation should not abandon the essentials and must consider customer requirements.

Enterprise technology innovation should highlight customer requirements

To be an innovation-oriented country in infrastructure, we must have a number of world-class research institutes, research-oriented universities and business incubators. For Chinese companies, indigenous innovation is not a new topic to discuss. But Chinese companies have long been baffled by a conundrum: what they must innovate on their own.

To deal with this problem, basically all the companies are to say that independent innovation. Chinese companies, such as Huawei's phones, are generally doing very well in these areas today. Whether it is the capital input of the budget, or the efficiency of the output rate are increasing day by day, to international standards firm ideals and beliefs.

As everyone knows, when the standard of comment is changed to the success of commercial service, people will find it embarrassing that there is basically no world-renowned enterprise in our country.

In plain English, there is no operation scale, but in the well-known brand. People have a bunch of "giants" that rank among the top 500 in the world, but they cannot find an enterprise like iPhone that has achieved successful leadership, controlled a certain sales market and won recognition and praise from customers all over the world according to the real relative path of sales market.

The world's second largest country with GDP can't just have one Huawei phone. Why have Chinese companies spent so many years and worked so hard on their own innovation, but struggled to rise to higher, more successful levels?

I don't think many Chinese companies realize that a hundred semicolons cannot be drawn immediately between the self-innovation they are proud of and the acceptance of the sales market and customers.

Today, the vast majority of people do not know where the headquarters of iPhone, Tesla Motors and BOSCH are, how their scientific research funds are invested, how their talent team is built, and how excellent their production lines are. However, this does not prevent people from trust, love and apply such well-known brands.

Why? Because the only concern of the customer is whether the company has given him the consideration of the requirements of the goods. Technical things, we do not know, do not understand, do not pay attention to. Instead of looking at this point, the company only wants to talk about it, immediately publicize the plan to customers and imperceptibly understand the "high and new technology" that only professional and technical personnel can understand, thinking that "I am so interested that you will buy it", only to get their confusion and disgust.

Many people may question: iPhone and Tesla are all new technology companies in people's image, and their success is not based on technology?

Carefully consider the path to the success of the iPhone, people will find that although the iPhone has high product research and development project investment, but the key to its development trend logic, not "high and new technology for the first", just all closely around commodity: to explore the requirements of customers, then find all to be able to consider this kind of technical requirements, regardless of the old and new, difficulty coefficient, applied to the quality of goods, design is good.

The iPhone that pioneered the new era of mobile phones, including key technologies such as touchscreen display, was not the original iPhone, and some of them even had been patented by Durant for years. The iPod, on which Steve Jobs was resurrected, also owes its high-capacity memory technology to the recycling of its inventor, a Malaysian firm. One of Steve Jobs's greatest strengths is not that he invented any high-tech technology, but that he understood it before anyone else: consumers expect easier access to their mobile phones, more music on their MP3 players, and then consider them in terms of merchandise.

The same is true of other global brands that have been successful. Many of their hot-selling products, and did not choose too many complex high-tech, but in the design scheme, processing technology has a unique style, the same to obtain customer recognition. Tesla cars contain crucial technologies, including rechargeable batteries, and are based on previous scientific research. But Elon Musk's grasp of customers' potential needs and integration of them into pure electric vehicles with cool exterior design has opened up a new category of sales market. Samsung's ability to slack off and catch up with the iPhone's dominance of smartphones is not based on the new technology being trumpelled today, but on understanding what customers want next and making the display bigger first.

Throughout, there was no doubt about the technical practicality. Without technological innovation, the creation of products will be difficult to implement, and companies will lose the indoor space and dominance to participate in market demand. But it is better to remember that these basic facts and the laws of business services will not change: the ultimate goal of technological innovation is still to produce goods that are genuinely relevant to the needs of the customer. If it is impossible to create a reasonable connection with customers and build a highway bridge between the two sides before and after communication with commodities, independent innovation with large capital investment will get twice the result with half the effort.

Welcome friends in the industry to exchange and learn!

In recent years, packaging machinery and equipment at the request of China's manufacturing industry showed a trend of growing, despite China's packaging industry to produce many, but relatively in our country hundreds of PET glass fiber adhesive tape machine is far from can consider requirements of many manufacturing industries, it is to bring plastic packaging machinery to produce a good breakthrough.

OPP coated aluminum foil tape machinery industry prospects in China can be expected in the future

In addition, the world's packaging with machinery has also entered an upgrade link. Bureau forecast analysis according to the size of population, to the United States in 2025 will develop into the aging society, the packaging world given to the elderly for packaging products potential requirements of customers, has just started to develop into an ageing population characteristics of packaging in the future, such as contains zip type seal, to open the metal material is a double cover TAB, packaging world to show customers a more convenient packaging.

In fact, the packing belt machinery is still not enough. In recent years, there is still a big difference between our country and overseas excellent standards, and it is urgent to improve. When the project investment for scientific research and development design accounts for 1% of the company's total sales volume, the company cannot survive; when it accounts for 2%, it can make do and maintain; and when it accounts for 5%, it can be competitive. However, the average investment for scientific research and development design of food packaging weapon equipment companies in China is less than 1%.

According to the survey, the national product research and development budget only accounts for 0.3% -- 0.5% of the company's sales, product research and development staff only accounts for 3.4% -- 4% of the practitioners, research institutes and institutions of higher learning experimental standards are out of date. Compared with the overseas scientific research investment level, the lack of scientific research investment in China may lead to the low level of automation technology and poor sales and market consideration ability in the food weapons and equipment manufacturing industry in China. Stand-alone version of products, less complete sets of equipment; More servers, less auxiliary boiler; The products with low science and technology content are more, the products with high technology, high benefit and high production efficiency are less; Rough processing machinery and equipment, less production and processing machinery and equipment; Generality models, special requirements, unique raw material production and processing of the model is less. Compared with similar foreign products, the product performance is low in production and high in energy consumption. The average energy consumption is 4-6 times that of capitalist countries. Especially in large and medium-sized complete sets of equipment performance difference is bigger, China's more excellent models of its production is about 1/2 of the overseas excellent level, and in China's food weapons and equipment overall technical strength behind the capitalist countries about 20 years.

In fact, it is not urgent at the moment. After the rapid development trend of China's packaging industry, many high-tech complete sets of equipment are still imported. Every year, many foreign exchange transactions are used to import high-grade machinery and equipment of complete sets of equipment. For example, plastic film double drawing machine equipment, a production line of the nearest principle of 100 million dollars, from the 1970s just began to introduce, so far, China has been importing 110 such production lines. In addition, there are also many applications of sterility testing boxes, filling machine in the dairy industry are basically produced by an overseas enterprise. The problems that machinery and equipment must deal with are not unique to our country.

PP packing belt is a commonly used material in logistics, mainly used for packaging packaging. PP packing belt with high performance, high tensile strength, can ensure that the load is strong enough, tension relaxation is small, combined to ensure that the long-term not loose. Today, I'm going to talk to you about regular plastic bags. 

How to choose the material of PP packing belt

The connection method of plastic packing belt usually has three kinds: hot melt method, clasp ring method and binding method. Manual packing belt is mainly for ordinary dimensional accuracy requirements, baler strength requirements are ordinary, can choose waste plastic production, appropriate to add some fillers. The dip Angle can also be slightly higher, the general thickness is below.3 mm, the width is about 5-25 mm, and the commonly used method is the fastening connection.

PP packing belt with the main dimensional accuracy and strength is very high, small deflection, and hardness, size thickness is generally mm, width of about 3 mm, often use hot melt and method connection, and the choice of raw materials is not suitable for more packaging, baler thickness can not be too thick, in case of hot melt temperature is too high.

The production process of PP packing belt is generally as follows: extrusion - cooling - one hot drawing - hot setting treatment - two hot drawing - hot setting treatment - product.

Packaging tape commonly used in the production of plastic raw materials: PP, HDPE, PVC, PET and nylon, etc., most of the PP polypropylene resin has been used at present. The dose is more than 90%.

The following are the main advantages of polypropylene resins. The typical formula of PP packing belt is all polymer, PP waste can also be selected through artificial packing belt, calcium carbonate as packing choice, baler can add light stabilizer for outdoor packing belt.

Here are two recipes for reference only.

1.PP packing tape. PP particles,PP powder,APP masterbatch 5%, casting 0.2%, triphenyl phosphate 0.2%, white oil 0.2%, which are important components.

2.PP artificial packaging waste PP, casting 0.5%,APP main material 90%, white oil 0.2%. Handband can also be used as waste woven bag PP material production.
