Shrink Bundling Film

We manufacture shrink films for unitizing, most commonly for trays of cans or bottles reducing corrugated usage.

Multiple – packs or “bulk” packs are also a popular application for industrial shrink film. Unless otherwise specified, our films have  minimum transverse direction (TD) shrink, good “stackability” and are sold by NET WEIGHT with honest yield thereby usually providing a cost savings.

** Vented Shrink Film now available **

Some shrink film applications require vents to evacuate air in the package. We can now vent shrink bundling film and centerfold with 1/16 inch holes on three inch centers. This pattern can be customized by adding or removing the perf needles.

Unlike most American extruders, we consider shrink film to be a performance application and not a commodity.  For each specific application we run the same resins with the same extrusion conditions every time to ensure consistent performance and continuity of supply.  Many customers have different requirements within the same facility, so we often make different films ( MD/TD shrink ratios, COF, etc ) destined for the same plant.

Trust your shrink film supplier with weights and measures ? Many extruders of shrink film in the US sell shrink film by "gross weight" defined as a full 10% over gauged plus the tare weight of cores, stretch wrap and pallet. So the true cost per package is up to 15% more than the low price on the invoice. This became common practice in the 1970's and is still often listed in the fine print of terms and conditions of sale. Caveat emptor if your supplier takes advantage of the information asymmetry and does not mark both the footage and weight on each roll. Bag makers and other converters are savvy about what is known as yield, or area derived from a specific number of pounds of a given thickness. Industrial users who buy film by the pound and cut off to make packages are in effect converters. Without the mathematical tools, it is impossible to audit yield. At Brentwood Plastics, we grew up making film for bagmakers and joined the shrink film party late. Honest yield is a given. And we don't charge extra for the quality which is requisite for the demanding converting industry. For DIY audit tools, check out our Handy Math tools.
