Advantages of PET Film

(1) Careful and transparent, reflecting the image of goods.

(2) Tight packages, good dispersion resistance.

(3). Rain proof, moisture proof and mildew proof.

(4) It has no recoverability and anti-counterfeiting function.

Heat shrinkable polyester film is often used in convenience food, beverage market, electronic and electrical appliances, metal products, especially shrinkage label is its main application field. With the rapid development of PET beverage bottles, such as cola, sprite, fruit juice and other beverage bottles need PET heat shrinkable film to be matched with them for heat sealing labels. They belong to polyesters and are environmentally friendly materials and easy to recycle.

Besides being used as shrinkage label, heat-shrinkable polyester film has also been used in the packaging of daily commodities in recent years. Because it can not only protect packaging items from impact, rain, moisture and rust, but also make products to win customers with exquisite printed packaging. At the same time, it can well show the good image of manufacturers. At present, more and more packaging manufacturers use printed shrink film to replace the traditional transparent film. Because the printing shrinkage film can improve the appearance of the product grade, is conducive to product advertising, can make the brand in the hearts of consumers have a deep impression.

Technical parameters of PET film

PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial film, packaging decoration, screen protection, optical mirror surface protection and other fields. Type of high temperature resistant polyester film: FBDW (single-sided dumb black) FBSW (double-sided dumb black) high temperature resistant polyester film specifications, thickness, width, inner diameter of coil core, 38um~250 um, 500~1080mm, 300mm~650mm, 76mm (3"), 152mm (6"). Note: Width specifications can be produced according to actual demand. The conventional length of membrane coil is equivalent to 3000m or 6000 of 25 micron.

Chinese Name: High Temperature Resistant Polyester Film

Foreign Name: PET

PET film production process

1. First, the original PET film is arranged into a single product into the conveyor line, and then through the feeding device into the die.
2. Because the shape and outer diameter of the product are not uniform, the accuracy of the labeling machine is highly demanded. At present, the double positioning guide system which has appeared in the world can solve this kind of problem perfectly, making the qualified rate of labeling up to 99,9%.
3. Adopt synchronous feeding device. Feeding is more stable. Automatic alarm and linkage control solve the problem that the machine will continue to operate when a fault occurs.
4. Because of the particularity of this kind of products, the electrothermal shrinkage is adopted. But electrothermal shrinkage is generally more difficult to control than steam shrinkage. Wrinkles and uneven heating of vortices will occur. In addition, the product's external diameter is not uniform, and the size of the selected label is much larger than that of the conventional label. This brings great difficulty to shrinkage. However, this problem can be solved by rotating step-by-step contraction.
