Introduce the technical features and transportation instructions of heat shrinkable film.

           The effect that heat shrinkable film can present is more and more beautiful, and its functionality is stronger and stronger. With the improvement of the quality of life and the diversification of packaging films, the requirements for shrink films are also higher and higher. heat shrinkable film is used for the sales and transportation of various products, and its main function is to stabilize, cover and protect products. Heat shrinkable film should have high puncture resistance, good shrinkage and corresponding shrinkage stress. In the process of shrinkage, the film can not produce holes. Because shrink film is often suitable for outdoor use, it is necessary to add UV agent. It has high flexibility, not easy to be damaged, strong explosion resistance, strong impact resistance, strong tear resistance and strong tensile force, and can replace box packaging. The shrinkage rate is high, and the articles can be tightly wrapped after thermal contraction. If the PE through bag (the opening at both ends of the bag) is made, after thermal contraction, the articles can be lifted at both ends of the opening, which can bear the weight of 15KG and is convenient to carry. Good transparency and good light transmittance can display products, indirectly promote products, and at the same time reduce distribution errors in logistics links. Moisture-proof, water-proof, dust-proof, which can not only achieve the packaging effect, but also beautify and protect products.

The following aspects should be paid attention to during transportation in heat shrinkable film:

• 1, make sure the package is complete.

• 2, prevent collision and extrusion.

• 3, avoid the sun and rain.

• 4, Keep away from heat sources.

        Nowadays, the heat shrinkage technology has developed to the point that almost all kinds of commodities can be packaged with plastic shrink film. In addition, shrink packaging is also used to make shrink labels and shrink bottle caps, so that containers that are not easy to print or have complex shapes can be labeled. This is also because heat shrinkable film is made of vinyl PVC resin mixed with more than a dozen auxiliary materials and then inflated twice, which is characterized by good transparency and easy shrinkage. , the shrinkage rate can be freely adjusted according to the needs of users, and the operability is strong. High transparency, so the label has bright color and luster. Good flexibility and stretchability, strong wrapping ability and convenient use; High puncture resistance and toughness. High elasticity. Anti-tearing. The shrinkage rate is large and good; Good heat sealing performance. Suitable for manual operation. And semi-automatic and high-speed full-automatic packaging; It is dustproof and cold-resistant, suitable for storage and transportation of packaged goods in cold environment, and reduces the damage during transportation. Collapse. Packet phenomenon, etc. Clean and can be used for food packaging.

The characteristics of thermal shrinkage membrane technology are as follows:

• 1, the shrinkage rate is large, and it can tightly wrap the articles after heat shrinkage. If it is made into a PE through bag (the openings at both ends of the bag), after heat shrinkage, the articles can be lifted at both ends of the openings, which can bear the weight of 15KG, and it is easy to carry.

• 2, the transparency is good, the light transmittance is good, the products can be displayed, the products can be indirectly promoted, and the distribution errors in the logistics links are also reduced.

• 3, moisture-proof, water-proof, dust-proof, can not only achieve the packaging effect, but also beautiful products, protect products.

• 4, Clean, odorless and energy-saving packaging materials.

         In the production process of heat shrinkable film, it is stretched in a high-temperature environment, then cooled sensitively, and then it is shaped. When in use, it is heated again, but it retracts to its original posture, with uneven heating, different shortening degree and planning. At first, extrusion blow molding or extrusion casting method should be used to produce the thick film, and then the thick film should be sufficiently softened at the melting temperature, and then stretched horizontally and longitudinally.

         Heat shrinkable film high-temperature masking tape heat shrinkable film is often used for painting, baking leather processing, coating and masking, fixing in the process of electronic parts, printing circuit boards and high-temperature processing masking. Since heat shrinkable film is so popular, what are the advantages of product packaging? Let's tell you about the advantages of using heat shrinkable film packaging?

• 1, heat shrinkable packaging can package special-shaped products that are difficult to package by ordinary methods.

• 2, the heat shrinkable film is close to the commodity after contraction, and the package is compact and can show the appearance of the commodity, and the packaged commodity is beautiful.

• 3, heat shrinkable film packaging has good sealing, moisture-proof, stain-proof and rust-proof functions, which can prolong the storage area of food for easy storage and outdoor stacking.

• 4, heat shrinkable film can provide 360-degree multi-angle decoration for packaging containers, and can print product information such as product descriptions on labels, so that consumers can understand the performance of products without opening the packaging bags.
