Polyethylene Shrink Wrap film

Polyethylene Shrink Wrap film is a tough and durable transit film with an exceptional strength and protection. Therefore the polyethylene Shrink wrap film is ideal for a variety of mainstream markets including the food and drink, personal care and industrial based sectors. We can offer high quality flexographic print up to 10 colors. This polyethylene Shrink Wrap Film can be micro perforated in order to avoid condensation. This Shrink Wrap film is fully Recyclable.

Shrink films are additionally used as case and tray overwrap to protect products during transportation and storage and are typically removed before the products are placed on store shelves. Shrink films are commonly utilized in applications formerly served by paper or corrugated cartons.

The use of shrink film for unitization of consumer products is the area of largest demand, with new applications for shrink film constantly being developed. Consumer appreciation of the convenience and cost savings of purchasing products in bulk has spurred the popularity in demand. Also, the continued popularity of superstores, warehouse stores, and wholesale clubs has contributed to bulk bundled products being offered to the public.

TECHNOLOGY TRENDS

The cast film extrusion process allows greater control of shrink film gauge uniformity, increased clarity, and higher output rates than the blown film extrusion process. Another benefit of cast film extrusion is the ability to produce shrink films with less shrink force in the TD, since most of the potential shrink force is limited to the MD. Shrink films produced with the cast film extrusion process are often called “low force” shrink films and are used for applications such as magazine overwrap. Over contraction of shrink films in those types of applications can cause the magazines to wrap or buckle when the outer packaging is heat shrunk.

The use of multi-layer, coextruded film construction affords many benefits over monolayer film. This includes the ability to further downgauge and to construct films with different levels of COF on the inside and outside layers of the film. Coextruded shrink film ranges from two layers to seven layers, with three-layer structures being most typical. Some producers of shrink film coextrude PE resins with polypropylene (PP) resin in either two or three-layer constructions, such as PP/PE (AB configuration) or PP/PE/PP (ABA configuration).

Other reported coextruded structures include low density PE (LDPE) and LLDPE in three-layer constructions (LDPE/LLDPE/LDPE [ABA]), and PP resin with LDPE-ethylene vinyl acetate copolymer (LDPE-EVA copolymer) resin in a PP/LDPE-EVA copolymer/PP resin configuration.
