PVC heat shrink film in the application of pharmaceutical packaging

Pharmaceutical products are usually bottled, then boxed, in the box outside there will be a layer of film, which is what we usually say heat shrink film, heat shrink film for packaging is already a very common thing, PVC heat shrink film can be re-packaging process, slightly heated, it can be very good to wrap the product.

Heat shrink film in the pharmaceutical packaging applications are very much, in addition to single-layer packaging for food and pharmaceuticals, but also for PVC / LDPE medicine ampoule with composite base film. pvc packaging film can also be used for container bags, box packaging, industrial packaging.

Heat-shrinkable film is currently the world's most widely used packaging products, with the following characteristics:

   (1) good transparency, can let the customer directly watch the situation of the packaged products, to facilitate the exhibition and purchase;

   (2) Close to the shape of the goods, is the so-called skin packaging, can be applied to a variety of complex shape of the goods packaging;

   (3) Excellent dustproof and anti-theft properties;

   (4) A variety of different sizes and shapes of goods can be packaged in a shrink-wrapped bag to prevent small items from being lost, but also easy to carry;

   (5) can be packaged according to the performance, shape, weight of different commodities and choose different resin type and additives, the production of different thickness, shrinkage and shrinkage rate, different tensile strength and impact strength of  heat shrink film, to fully meet the various requirements of commodity packaging.

At present, the production process of PVC heat shrinkable film is becoming more and more rigorous, PVC heat shrink film can also be directly from the extruder after extrusion of thick film, slightly cooled to 115-145 ° C (unplasticized Pvc) high elasticity of the state of direct unidirectional or bi-directional stretching to become a contraction film, only a slight change in the mouth of the mold that can be implemented. pvc to meet the environmental protection requirements, and continue to other product Packaging development, become a representative product of the heat shrink film.
