Brief introduction and application of PVC Heat Shrinkable film

In the 21st century, with the rapid development of plastic films, PVC Heat Shrinkable film has more and more application fields, including agricultural greenhouses, product packaging and so on. The reason why it can be so widely used is that, the main reason is that it has the following advantages:

* wrap the goods stacked on the pallet to make the packaging more stable and tidy and more waterproof;

* has the characteristics of high tensile strength, high elongation, good self-adhesion, high transparency, etc;

* shrink film, Heat Shrinkable film is mainly made by mixing and extruding several different brands of polyene resin, with puncture resistance, super strength and high performance;

Heat Shrinkable film Contact film technology mainly refers to some main steps in the production of Heat Shrinkable film blowing film, such as extrusion, molding, cooling, traction and winding and Other Heat Shrinkable films. The multi-layer planar superposition head mentioned in this paper has a large heat absorption area and a good plasticizing effect due to the double number of extrusion layers, naturally, the output will be increased, supplemented by the improvement of cooling technology, and the output can be increased by 50%.

PVC Heat Shrinkable film has some shortcomings. For example, some pvc Heat Shrinkable films are very soft when used in summer and harden in winter; Some Heat Shrinkable films are easy to absorb dust and become opaque; Some PVC Heat Shrinkable films have a short service life, are easy to age, cannot withstand wind and frost attacks and sun exposure, and are easy to crack on the surface. The application of PVC Heat Shrinkable film is still very extensive. I believe that as the technology of Heat Shrinkable film becomes more and more mature, Heat Shrinkable film will be applied in more fields.
