NY/AL/CPP Foil Bag

NY/AL/CPP foil bag is a high-grade four-side sealed composite aluminum foil bag made by laminating nylon film,pure aluminum foil and cast polypropylene film through advanced dry compounding technology.As a high-strength and high-barrier flexible packaging material,it is famous for excellent puncture resistance,low temperature resistance,oil resistance and high-temperature cooking resistance,widely used in high-end food vacuum packaging,frozen food,cooked food,seafood,meat products and high-demand industrial packaging fields.

The three-layer structure brings distinct professional functions respectively.The outer NY nylon layer features ultra-high toughness,strong tensile strength and outstanding puncture resistance.It is not easy to be pierced by hard food bones,sharp edges and granular contents,effectively avoiding package breakage and liquid leakage during extrusion,folding and transportation.It also has good low-temperature resistance and stable mechanical property even in freezing environment.The middle AL pure aluminum foil layer acts as the core barrier layer,achieving full light shielding,complete oxygen isolation,superior moisture-proof and odor-blocking performance.It can completely isolate external light,air and water vapor,effectively prevent internal items from oxidation,discoloration,mildew and flavor deterioration,and greatly extend the preservation period.The inner CPP cast polypropylene layer is high temperature resistant food-grade material,which owns stable heat sealing performance,excellent oil resistance,acid and alkali resistance.It can withstand high temperature steaming,boiling and retort sterilization,and will not deform,melt or release harmful substances under high temperature conditions.

Compared with ordinary PET/AL/PE aluminum foil bags,NY/AL/CPP composite bags have obvious upgraded advantages.It is far superior in toughness,cold resistance and high temperature resistance,suitable for deep freezing storage below minus 20 degrees Celsius and high temperature cooking above 120 degrees Celsius.It has strong oil-proof performance,perfect for packaging oily,greasy and marinated food,effectively preventing grease penetration and bag body damage.Its sealing edge is firmer with better pressure resistance,suitable for vacuum pumping packaging,which can fit tightly with products and remove air thoroughly to realize fresh-keeping storage.

In practical application,this kind of foil bag is the preferred packaging for cooked meat,braised food,seafood products,quick-frozen ingredients,pickled vegetables and high-end nutritional food.It is also widely used in packaging high-precision electronic components,military supplies,medical disinfection products and special chemical materials that require strict moisture-proof,anti-oxidation and low-temperature storage.The surface can be printed with exquisite patterns,brand information and product specifications,combining practical protection and commercial display effect.

All raw materials of NY/AL/CPP foil bags strictly comply with international food safety and environmental protection standards,non-toxic,odorless and harmless to human body.It supports various customized sizes,styles and sealing types,and matches well with automatic vacuum packaging machines for efficient mass production.

With the continuous upgrading of food preservation and high-standard packaging demands,NY/AL/CPP high-temperature resistant aluminum foil bags have become indispensable high-performance packaging products in the market.Relying on strong structural stability,all-round protective performance and wide environmental adaptability,it has become the mainstream choice for medium and high-end packaging,enjoying great popularity in domestic and overseas packaging markets.
