What material is usually packing bags of nuts?

Nut bags are generally multilayer composite materials, mainly divided into; Lining material: PE ( Chinese name polyethylene) Polyethylene odourless, non-toxic, feel like wax, has good low temperature resistance, The lowest temperature can reach - 100 - - 70° C) , most alkali erosion ( No acid) with characteristics of oxidation resistant At room temperature with good chemical stability, have certain characteristics of the resistance to acid, alkali and does not dissolve in any solvent. Can direct contact with food, often used as a food packaging composite heat sealing layer material. The middle layer material: PET ( Chinese polyester) Polyester is characteristic of high temperature resistance, good printing, easy processing, resistance to voltage by good insulation and high transparency, film surface level off is smooth, good mechanical properties, high rigidity, hardness and toughness, durability, friction resistance, high temperature and low temperature resistance, chemical resistance, oil resistance, good air tightness and sweet, is one of the permeability resistance of composite film base material. Permeable rate of the PE film is poorer so often choose air tightness good PET film with compound, increase the resistance capability. And the outer layer material requirements relative to the lining materials is not so high, mainly in accordance with the following features, bag making, printing, composite, relatively stable chemical properties. With the material of outer collocation: BOPP ( Chinese name two-way stretch polypropylene film) Characteristics of high transparency and gloss, excellent printing ink and coating adhesion, heat sealing strength, water vapor and oil cut off performance, uv blocking performance, pearly luster of high-grade appearance, high barrier property low static performance. BOPP is dumb light effect, similar to the people often say that grind arenaceous effect, one kind is the light effect ( YOPP) 。 Kraft paper, the characteristics of high hardness, good texture, made from stereo packet is better, good for product promotion and sales, but the cost is higher. AL( Aluminum foil) Characteristic quality of a material soft, good ductility, has a silver sheen, moistureproof, airtight, shading, resistance to abrasion, incense, and non-toxic tasteless! Nuts packaging materials are generally based on functional USES to determine, for example to sealed container, the characteristics of fresh fragrant will need to choose PE, PET, VMPET, AL composite materials, etc. Different material collocation, of course, the price is not the same, want to understand nut bags higher ratio of material collocation!
