Food film

The three most common materials are PE (Polyethylene), PVC (Polyvinyl Chloride), and PVDC (Polyvinylidene Chloride). PE film is the most widely used for household applications due to its safety and recyclability, though it has lower oxygen barrier properties. PVC film offers superior stretchability and clarity, making it ideal for supermarket produce, but it must not be used with high-fat foods or in microwaves due to potential plasticizer migration. PVDC provides the highest oxygen and moisture barrier, significantly extending shelf life, but comes at a higher cost point.

For the US market, products must be FDA 21 CFR 177.1520 compliant. For the EU, they must adhere to Regulation (EU) No 10/2011 regarding plastic materials intended to come into contact with food. It is critical to ensure the supplier provides a Declaration of Compliance (DoC) and Migration Testing Reports (Total and Specific Migration Limits) from accredited third parties like SGS, TUV, or Intertek.

Key performance indicators include Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR), which determine food preservation quality. Additionally, check for Anti-fogging properties (essential for refrigerated displays), Tensile Strength, and Elongation at Break. For automated packaging lines, the COF (Coefficient of Friction) must be optimized to prevent machine jamming.

There is a significant shift towards Biodegradable and Compostable films made from PLA (Polylactic Acid) or PBAT. Buyers should look for certifications such as EN 13432 or ASTM D6400. Another option is Recyclable Mono-material PE films, which align with global circular economy initiatives and help reduce Plastic Tax liabilities in regions like the UK and EU.

Always request a Pre-Shipment Inspection (PSI) focusing on thickness consistency (gauge) and roll length verification. A common industry risk is 'short-rolling,' where the actual length is less than stated. Use Made-in-China.com's Secured Trading services to ensure payment is only released after the inspection report confirms the goods meet your specifications.

Negotiate based on Raw Material Index Pricing (e.g., LLDPE futures prices) to ensure transparency. For bulk orders, aim for a tiered pricing structure where the unit price drops as volume increases. Request OEM packaging (custom branded boxes and cores) to be included in the FOB price to enhance your brand's market presence without extra logistics costs.

Food film is sensitive to extreme temperatures and humidity. Ensure the container is clean and free of odors, as plastic can absorb scents. Request heavy-duty palletization with edge protectors to prevent the rolls from being crushed or deformed during transit, which would render them useless for automated dispensing machines.

Prioritize Audited Suppliers on Made-in-China.com who have undergone on-site verification of their production facilities. Verify their ISO 22000 or BRC (British Retail Consortium) food safety management certifications to ensure the manufacturing environment meets global hygiene standards.
