PVC shrink film bag is the most commonly used heat shrink material in heat seal packaging. Through hot air blowing, the highly transparent heat shrink film can be tightly attached to the surface of the item, thus improving the product grade, dustproof and moisture-proof, and making the item present a new and perfect packaging effect.
Easy to use and high efficiency: Due to the use of green and environmentally friendly stretch film and pre-stretch technology, it is quite labor-saving to use, without the need for special packaging machines and special packaging sites.
At the same weight, the length of each roll of this environmentally friendly stretch film is more than twice the length of each roll of ordinary stretch film, which can reduce the frequency of changing film rolls during packaging and also save costs in transportation, packaging and distribution.
Due to the unique properties of PVC (rainproof, fireproof, anti-static, easy to mold) and the low input and high output of PVC, it is widely used in the building materials industry and packaging industry.
Heat shrinkable film has high transparency, good gloss and shrinkage. High rate and high characteristics.
PVC shrink film factory production shrink film, PVC shrink film suppliers recommend that you pay attention to the following points.
1. The die head must be cleaned and no burnt plastic must fall into it. If the naked eye can find it, it must be removed immediately.

4、Minimize the appearance of surface wrinkles and white tight lines in the middle to avoid affecting the beauty.
5, cut edges to neatly, uneven stretching of the film can not be shipped as finished products.
①Mechanical properties: strong, light weight, durable, scratch resistant.
②Chemical properties: atmospheric resistance, chemical and biological testing, insulating properties, resistance, heat insulation, noise reduction.
③Other physical properties: waterproof, oil-proof, airtight. Can be folded into rigid or soft, transparent or opaque products upon request; high frequency welding or heat sealing; easy to color and print.
④Processing performance: easy to use all processing techniques in current plastic processing. Such as injection molding, extrusion, ring molding, calendering, rotational molding, coating, etc.
With the development of the shrink film market, the homogenization of shrink film products is becoming more and more obvious, and the differences between the shrink films produced by various shrink film manufacturers are becoming smaller and smaller. Therefore, more efforts on shrink film packaging can highlight the product theme and attract consumers. In the segmented shrink film market, the design of PVC shrink film that meets the market demand for different types of shrink film reflects a manufacturer's marketing ability.
With the widespread use of PVC shrink film in daily life, manufacturers should meet the requirements of simplicity, practicality, environmental protection and environmental protection from the beginning of packaging design. Thus reducing carbon emissions and achieving sustainable economic development. With the widespread use of PVC shrink film in daily life, manufacturers should meet the requirements of simplicity, practicality, environmental protection and environmental protection from the very beginning of packaging design.
