What is the role of PET shrink film?

Introduction and application of PET heat shrinkable film:
PET heat shrinkable film is a new type of heat shrinkable packaging material. Due to its easy recycling, non-toxicity, odorlessness, good mechanical properties, and especially environmental protection, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrinkable film. However, the ordinary polyester is a crystalline high polymer, and the ordinary PET heat shrinkable film can only obtain a heat shrinkage rate of 30% or less by a special process. To obtain a polyester film with a higher heat shrinkage rate, it must also be modified. That is, in order to prepare a polyester film having a high heat shrinkage ratio, it is necessary to copolymerize a common polyester, that is, polyethylene terephthalate. The copolymerized modified PET Film has a maximum heat shrinkage rate of more than 70%. Characteristics of PET heat shrinkable film type polyester film: It is stable at normal temperature, shrinks when heated (above glass transition temperature), and is more than 70% heat shrinkage in one direction.
The advantages of PET shrink film are:
1 rain, moisture, mildew.
2 tightly packed with good anti-scattering properties.
3 no recovery, there is a certain anti-counterfeiting function.
4 body transparency, reflecting the image of the goods. Heat shrinkable polyester film is often used in the convenience food, beverage market, electronic appliances, metal products, especially shrinkage labels are its main application areas. Because with the rapid development of PET beverage bottles, beverage bottles such as cola, sprite, and various juices need PET heat shrinkable film to be used as a heat seal label. They are all polyester-based, environmentally friendly materials, and easy to recycle. use. In addition to being used as a shrink label, PET heat shrinkable film polyester film has also been used in outer packaging for daily use products in recent years. Because it can protect the packaged goods from impact, rain, moisture, rust, and the product can win the user with a beautifully printed outer packaging, and it can show the good image of the manufacturer. At present, more and more packaging manufacturers use printed PET heat shrinkable film to replace traditional transparent film. Because the printing shrink film can improve the appearance of the product, which is conducive to the advertising of the product, which can make the brand of the brand deeply impressed in the hearts of consumers.

The unique advantages of our PET heat shrinkable film:
1. Independent production and price advantage. All of our products are produced independently and have a good cost control system to achieve the lowest price.
2, the intersection of cooperation, for your consideration. According to different orders of customers, in order to produce different products, it can be produced according to customer orders, ranging from small to hundreds to millions, ranging from one centimeter to five or six meters, even modified machine production. Special specifications are for you.
3, fast response, time advantage. Orders in the morning, the fastest afternoon delivery, can solve the urgent needs of customers.
4. Every colleague of the company adheres to the principle of “honesty, professional service, customer-oriented, mutual benefit and mutual benefit”. The pre-sales and after-sales service is a high-quality service for each customer.
