Heat shrinkable film function is good, and the welding sealing range is wide, good weldability at low temperature. Heat shrinkage rate > 50%, the various special products with just the right amount of heat shrinkable film molding machine, packaging and natural. Unique because of the three layer compound oxygen insulation layer, breathable, moisture permeability, good barrier property, and is infected with dirt not easily; High transparency, good gloss, can progress product packing grade; Good heat sealing, homework easily, not easy broken membrane.

The use of heat shrinkable film packaging products along with the development of the era, is becoming more and more towards lightweight, environmental protection, the development of the enterprise must do and environmental protection harmonious together, don't forget to at the same time in the development of environmental protection. Lightweight heat shrinkable film packaging can relieve people concern about environmental protection and sustainable development, more and more people choose packing is better, faster production, itself strong and reduce weight products, when cosmetic wholesale sales products, each the slightly reduce the dosage of resin on the package can bring considerable economic benefits for the enterprise, especially resin raw materials price under the premise of unprecedented increase, more and more enterprises of packaging lightweight issue increasingly keen interest.

In order to reduce low thermal shrinkage film bottle or cover of the resin, injection molding process needs to change, to choose and materials for injection molding technology instead of the back buckle injection molding technology, complete container cap injection molding process, will be the center of the mould stripping away strip, change the screw thread bottle cap, so that it can reduce the weight of the lid, achieve the goal of lightweight.

Shrink film is used in various products sales and transportation. Its main function is stable, cover and protection products. Shrinkable film must have high durable sex, good contractility and contraction stress. In the process of contraction, film does not produce holes. Because the shrinkable film often are suitable for outdoors, so you need to add UV ultraviolet resistant agent.

PET type heat shrinkable polyester film features: it is stable at room temperature, heating contraction (more than glass transition temperature), and is in one direction more than 70% of the thermal contraction. The advantage of heat shrinkable polyester film packaging is: stick put oneself in transparent, merchandise image. The tight packing, good dispersion. Waterproof, moistureproof, mouldproof. No resilience, have certain anti-fake function. Convenient heat shrinkable polyester film is often used in food and beverage market, electronic appliances, metal products, especially the shrinkage label is the main application fields. Because with the rapid development of PET bottles, such as coke, Sprite, all kinds of fruit juice beverage bottle needs to be a set with PET heat shrinkable film do the heat sealing label, they both belong to polyester class, is environmentally friendly material, easy recycling use.
