Shrink wrap film is available in a variety of types, thicknesses, clarities, strengths, and shrink ratios, which can be employed alone or in conjunction with one another to create the precise type of layering and protection for your product. These options and constructions have broadened over time to accommodate specific requirements for sealability, optics, toughness, slip, temperature, force, and memory.
Advantages of single-layer Polyethylene film
Unlike multilayered films, single-layered films ensure against a material failure of plastic bags due to delamination, offering higher purity, greater compatibility, and increased safety for critical and high-value process materials and final biopharmaceutical agents.
Advantages of multi-layer Polyethylene film
With the proper selection of raw materials three-layer Polyethylene film gives better optical (transparency, shininess…) and mechanical (toughness) characteristics with the reduced thickness (20-30 % less thickness then mono layer film). The Polyethylene film is been sold by it weight and been used by its length and that means significant financial saving. Plus because of the reduced thickness in process of packaging buyers get more film in a roll which means fewer roll changes, less needs for storage space and less packaging waste
