Steps to Use POF Folded Film in Cold Storage Without Cracking

Step 1: Select the Right Film Grade

• For -18℃ Freezers: Guangdayuan’s LDPE-modified POF (thickness 60μm), used in Kuwaiti meat packing.
• For 0-4℃ Refrigeration: EVA-blended POF (40μm), ideal for Malaysian fruit exports.
• Anti-Static Option: Additive-treated film for Indonesian electronics cold logistics.

Step 2: Optimize Shrink Processing

1. Preheat Film: 30℃ for 10 minutes in cold environments (common in Qatar’s winter).
2. Shrink Temperature: 170-180℃ (10℃ higher than standard) to enhance molecular alignment.
3. Cooling Rate: Use Guangdayuan’s rapid cooling fans (30m³/min) to fix low-temperature flexibility.

Step 3: Cold Storage Handling Tips

• Stacking Pressure: Max 5kg/m² to avoid film creasing in Saudi Arabian cold stores.
• Temperature Fluctuation: Avoid frequent -18℃ ↔ 4℃ shifts; use Guangdayuan’s thermal buffer films.
• Removal Technique: Peel at 30° angle to prevent stress cracking, as taught in Vietnam’s seafood factories.

Regional Success Stories

• A Dubai catering company reduced packaging waste by 40% using Guangdayuan’s cold-resistant POF.
• A Thai pineapple exporter extended overseas shelf life by 20 days with anti-fog POF films.

Why Guangdayuan?

• Complete Ecosystem: Films matched with shrink equipment and cold storage testing kits.
• Localized R&D: Dubai lab focuses on extreme cold; Jakarta lab on humid cold solutions.
• Warranty: 6-month guarantee against low-temperature brittleness for standard applications.
