Coextruded Products Some industrial applications require the enhanced strength that only a coextruded product provides. We use multiple layers of different materials to greatly improve impact resistance and tear strength versus standard films or bags, and our Modified Atmosphere Packaging (MAP) films and bags are the perfect solution for molding compounds, circuit boards, metal products and other items that must be protected from environmental forces.
Box and Barrel Liners Give us your requirements and we'll help size and specify liners for corrugated cartons or drums. Because we are a custom resource, you'll get precisely the size and strength you need for your application.
Top Sheets Available as individually cut or perforated on rolls, top sheets protect pallets from dirt and moisture. We can help you package your product for maximum durability.
Shrink Bundling Films Custom made to your specifications, our shrink bundling film provides an economical packaging system. The high shrink force and contact clarity protect against in-transit damage, pilferage and product tampering.
Pallet Covers We produce dependable polyethylene pallet covers with excellent puncture resistance so your products arrive safely at their destination. They're available in side seal, bottom seal, flat or gusseted bags so you get the best fit and most protection possible. Also available is a high-grade shrink version for tight product utilization and to reduce load shifting.
Machine Films Made from prime resin, our machine films offer the ultimate in flexibility. You can use centerfold films on most L-sealers, and our single wound sheeting is standardized for shrink wrappers. Mattress manufacturers benefit from several grades of machine wrap films. Our machine films are perfect for use on vertical form/fill/seal equipment.
Performance Products Our films can be formulated to meet rigorous requirements like automotive standard 302 or NFPA flame retardancy. Our antistatic films can meet military specifications or other static resistant requirements. For sunlight exposure, UVI film provides substantially longer use life. Light sensitive products require our photoblack film; impervious to sunlight. Many other performance attributes can be met with our ability to custom formulate various packaging films.
