Wipak offers a broad range of packaging solutions, from thermoforming, semi-rigid and flexible films to sustainable paper composites, lidding films, and reclosable films.
Multilayer Films that Resist High Temperatures
Wipak has developed a plastic laminate for high‑temperature applications that can be used to replace packages made from polyester (PET) and aluminum oxide (AlOx) and can be used in lidding and pouch applications. The composites are sterilizable to a temperature of 130 °C / 270 °F and can be heated in a microwave oven.
Wipak lidding films protect the quality and freshness of ready meals packaged in vacuum or under modified atmosphere (MAP). The Bialon range offers films that have been adapted to seal against C-PET trays. They offer an excellent drum effect, are temperature-resistant, and can be heated in a microwave or double-boiler. The peelable Biaxer XX AL product, made from polyester is suitable as a lidding web for uncoated aluminum trays.
Flexible Films and Barrier Films
Wipak multilayer films guarantee that protective gases cannot escape – cooled products stay protected longer. For example, Bialon XX is ideal for packaging fresh pasta and sauces. It is transparent, pasteurizable to 100 °C / 210 °F , robust (based on polyamide), and complete with an EVOH barrier layer. This means that the oxygen barrier is up to 10 times better than with painted films.
Lidding Films for PP Trays
Wipak offers a multitude of films for preformed trays. The type and thickness are selected to suit the application. If required, a high-barrier layer and/or anti-fog feature can be incorporated into the films, offering an excellent drum effect for the tray. Some types of film are temperature-resistant and therefore can be pasteurized or sterilized.
Thermoforming Flexible Films
Thin, efficient, and sustainable, NICE PP is the alternative to semi-rigid films. The thickness can be reduced by up to 35% from that of conventional films, with no decline in the excellent strength or shape properties. The NICE PP product can be processed by all packaging machines in common use. It is available in thicknesses of 210–500 μm and can be produced either with or without a gas barrier. Pasteurizable and sterilizable, NICE PP is suitable for hot-fill applications.
We also offer temperature-resistant film solutions for bag applications (stand-up pouches / flowpacks) based on aluminum. Thanks to newly developed sealing layers, Aluthen composites are suitable for hot-fill use and are pasteurization or sterilization. The exact features depend on the film type.
