High Temperature Resistant Foil Bag

High temperature resistant foil bag is a kind of professional high-barrier composite packaging specially made for high-temperature cooking,steaming,boiling and retort sterilization.It is mainly composed of nylon film,pure aluminum foil and cast polypropylene film,namely NY/AL/CPP structure.With excellent heat resistance,oil resistance and stable sealing performance,it can withstand high temperature sterilization without deformation,leakage or harmful substance precipitation,and is widely used in high-temperature cooked food packaging,sterilized food and high-temperature resistant industrial packaging fields.

The core advantage of this foil bag lies in its outstanding high temperature endurance.Different from ordinary PE inner layer foil bags that cannot resist high heat,the inner CPP layer has excellent high temperature stability,which can safely endure high temperature environment from 100℃to 135℃for a long time.It is not easy to soften,melt,shrink or crack during high-pressure steaming,boiling and retort processing,and always keeps intact bag shape and tight sealing state.The outer NY nylon layer enhances overall toughness and puncture resistance,effectively preventing sharp food residues from piercing the bag body during high temperature processing and transportation.The middle pure aluminum foil layer provides full light shielding,oxygen barrier and moisture-proof performance,which can completely isolate external air and light,lock the original flavor of food,and avoid quality deterioration during high temperature sterilization and long-term storage.

In addition to high temperature resistance,it has many superior comprehensive properties.It features strong oil resistance,acid and alkali resistance,suitable for packaging high oil content,marinated and savory food,effectively preventing grease penetration and bag damage.It has good low temperature resistance as well,adapting to both high temperature cooking and cold storage freezing,with wide temperature adaptability.Its heat sealing edge is firm and high-pressure resistant,not easy to open after high temperature treatment,effectively avoiding liquid leakage and air leakage.All raw materials adopt food-grade environmentally friendly formula,which will not release peculiar smell and toxic substances under high temperature conditions,fully complying with international food safety standards.

It has very clear and targeted application scenarios.In food industry,it is the preferred packaging for braised meat,stewed dishes,vacuum cooked food,meat snacks,seafood products,instant porridge and self-heating food.After high temperature sterilization treatment,the food can realize long-term room temperature preservation,greatly extending shelf life.It is also widely used in packaging high-temperature resistant medical supplies,special chemical reagents and high-temperature resistant electronic components in industrial fields to ensure stable product performance under harsh temperature conditions.

This high temperature resistant foil bag supports various customized sizes,thicknesses and printing designs.Common styles include high temperature resistant three-side seal bags,vacuum retort bags and stand-up cooking bags.It is perfectly compatible with retort sterilization machines,high temperature vacuum packaging machines and other professional equipment,meeting large-scale standardized production needs of food factories.

With the rapid development of instant food and ready-to-eat food industry,high-temperature sterilization packaging has become an essential link in food production.Relying on reliable high temperature resistance,excellent fresh-keeping barrier performance and safe food-grade material advantages,high temperature resistant foil bags have become irreplaceable core packaging materials in the sterilized food industry.It effectively balances food taste,safety and long-term storage demands,and has won long-term trust and stable orders from global packaging buyers.
