Customized Plain BOPP Food Packaging Materials Bags, Color : White

Food packaging bags come in various materials, each with unique properties suited for different types of food products. Here’s an overview of common food packaging materials used for bags:

• Polyethylene (PE) – Flexible, moisture-resistant, and commonly used for bread, frozen foods, and snacks.
  • Types:
    • Low-Density Polyethylene (LDPE) – Soft, flexible, and resistant to moisture (used for bread and produce bags).
    • High-Density Polyethylene (HDPE) – Stronger, more rigid, and used for grocery and frozen food bags.
• Polypropylene (PP) – Transparent, lightweight, and resistant to grease (used for snack foods, pasta, and baked goods).
• Polyethylene Terephthalate (PET) – Clear, lightweight, and strong (used for vacuum-sealed bags and beverage packaging).

• Kraft Paper – Eco-friendly, durable, and often used for dry foods like flour, sugar, and coffee.
• Wax-Coated Paper – Provides moisture resistance for items like sandwiches and baked goods.

• PLA (Polylactic Acid) Bags – Made from corn starch; biodegradable and used for fresh produce or snacks.
• Compostable Kraft Paper Bags – Made from plant-based materials, ideal for eco-friendly packaging.

• Aluminum Foil Bags – Provides excellent barrier protection against light, air, and moisture (used for coffee, chips, and pet food).
• Metalized Polyester (MPET) – A lighter alternative to aluminum foil, often used for snack foods.

• Stand-up Pouches – Made of multiple layers of plastic, foil, or paper for strength and resealability (used for nuts, coffee, and dried fruits).
• Vacuum-Sealed Bags – Extend shelf life by removing air (used for meat, cheese, and seafood).
