EVOH film for Meat Packing
One of food packing applicatons of EVOH film is for meat.Here we indtroduce more info about it.
EVOH film for meat products are flat bag packaging, stretch packaging, shrink packaging and MAP packaging atmosphere packaging.
Flat bag packaging is the original film sealed by the three sides of the bag. The contents of the charge into the nitrogen or vacuum after sealing. This package is generally used EVOH and polyolefin multi-layer co-extruded film, a good oxygen , Water blocking and fragrant function.
Stretch packaging is divided into cover film and base film, cover film EVOH and polyolefin multi-layer co-extruded film, without stretching. The base film is mostly EVOH, nylon and polyolefin casting co-extruded high barrier film, into the packaging and then vacuum, and then stretch molding, packaging close to the contents of the consumer can visually see the contents.
Shrink packaging for the use of fresh meat, the use of EVOH and polyolefin and nylon co-extruded into a multi-layer barrier film. 90% of the cold meat in developed countries using barrier packaging to extend the packaging freshness, color and taste.
MAP packaging consists of multi-layer barrier tray and high barrier film composition.it is filled with gas nitrogen, carbon dioxide and oxygen or other mixed gas, slow food oxidation, inhibition of microbial and fungal reproduction, to maintain myoglobin bright red color. The effect is better, mainly for fresh meat and processed meat products.
PE / PA / EVOH / PA / PE co-extruded film packaging sausage preservation of the best. EVOH film superior performance than glass bottles, tin cans and general plastic composite bottle packaging materials.
Glass packaging is fragile, transport risk, gross weight, should be affected by light and air color and composition changes. Tinplate packaging costs are too high, easy to transport deformation, the appearance of opaque, poor visibility, affecting the packaging beautiful. General plastic composite packaging of the poor sealing, high oxygen permeability, susceptible to oxygen,toxic and harmful products, but also easy to leak.
EVOH high barrier film low cost, visibility and sealing strong, easy to transport, to ensure food quality and safety.
In order to meet the new packaging regulations and new standards, to break the green trade barriers, consolidate and expand the export market, China’s food processing enterprises must update the packaging concept, strengthen environmental awareness, vigorously develop green packaging. EVOH high barrier multi-layer co-extruded cast film material is non-toxic, non-polluting, low energy consumption, low cost, easy to handle, recyclable. So it will be in the market to be more widely used.
