Food Packaging Bag Selection Guide
Food safety starts with packaging. An inadequate plastic bag can contaminate food before it reaches the consumer. This guide covers material properties, regulatory requirements, and bag type selection for food industry procurement professionals.
Why Food-Grade PE Is the First Choice
PE (polyethylene) is the mainstream material for direct food contact bags because it is non-toxic, chemically stable, temperature versatile (LDPE handles freezing, HDPE handles moderate heat), transparent for product visibility, and highly processable.
CHIN TZON Plastics uses PE raw materials meeting Taiwan TFDA "Food Utensils, Containers and Packaging Hygiene Standards" for all food-use products.
Bag Types for Food Applications
Flat Bags: Precision Portioning & Sealing
Most common in food portioning operations. Compatible with automatic/semi-automatic sealing equipment. Applications: bakery bags, frozen food portioning, bulk candy/snack packaging, seasoning sachets.
Vest Bags: Retail Takeaway
Carry handle design for quick customer handoff. Common in traditional markets, night market food stalls, and supermarket checkouts. Typical thickness 0.015-0.025mm.
Hole Punch Bags: Fresh Produce Display
Small holes allow gas exchange, preventing anaerobic respiration that accelerates spoilage. Used for bagged vegetables, fruit, and mushrooms in supermarket produce sections.
Food Packaging Regulatory Requirements
Verify with suppliers: food-grade raw materials (no recycled content), regular testing reports, hygienic production facilities, and migration limits within legal standards.
