Heat shrinkable film is used for the sale and transportation of various products, and its main role is to stabilize, cover, and protect the product. The shrink film must have high puncture resistance, good shrinkage, and a certain shrinkage stress. During the shrinkage process, the film cannot create holes. Because shrink films are often suitable for outdoor use, UV anti UV agents need to be added.


1、 Product features of heat shrinkable film:


1. The heat shrinkable film has high flexibility, is not easily damaged, has strong explosion resistance, strong impact resistance, strong tear resistance, and strong tensile force, and can replace box packaging.


2. The heat shrinkable film has a large shrinkage rate and can tightly wrap items after heat shrinkage. If it is made into a PE straight through bag (both ends of the bag are opened), after heat shrinkage, the two ends of the opening can lift items, and can withstand a weight of 15KG for easy handling.


3. The heat shrinkable film has excellent transparency and a light transmittance of 80%. It can display the product, promote the product invisibly, and reduce delivery errors in the logistics link.


4. Heat shrinkable film is moisture-proof, waterproof, and dustproof, which can not only achieve packaging effects, but also beautify and protect products.


5. The heat shrinkable film is non-toxic, odorless, and pollution-free, which is an environmentally friendly packaging material.


2、 Common specifications of heat shrinkable film:


Width of heat shrinkable film: 100mm-2400mm


Transverse tear strength: ≥ 40kN/m


Thickness: 20 μ m-250 μ M Longitudinal direction: ≥ 40kN/m


Horizontal shrinkage rate of heat shrinkable film: 5% - 55%


Tensile strength Transverse: ≥ 12MPa Longitudinal: 50% - 80% Longitudinal: ≥ 12MPa


Shrinkage temperature of heat shrinkable film: 150 ℃ - 220 ℃


Elongation at break: ≥ 200%


Specific gravity of heat shrinkable film: 0.93g/cm3 76mm


Inner diameter of coil core: 76mm


3、 Use of heat shrinkable film:


Heat shrinkable film is widely used in the outer packaging of various products such as food, medicine, disinfected tableware, cultural and sports goods, craft gifts, printed goods, hardware and plastic products, telephones, electronic appliances, and so on. Especially in the combined (bundled) packaging of irregular shaped items or commodities, it can not only meet the functions of moisture and dust prevention, anti touch theft, transparent display, and other functions of commodities, but also increase the appearance attractiveness of products, It can also be used to replace various types of paper boxes, not only saving packaging costs, but also meeting the packaging trend. Shrinkage film (bags) can be processed into: flat bags, arc shaped bags, trapezoidal bags, three-dimensional bags, and other special-shaped bags.
