– Economical, flexible, and suitable for general use
– Ideal for filling temperatures of 60–80°C -
Clear NY/PE (Nylon/Polyethylene)
– Food-grade, higher puncture resistance
– Suitable for liquids, food processing, and chemicals -
Aluminum Foil (High Barrier Film)
– PET/AL/PA/PE: For normal temperatures
– PA/AL/PA/PP: For high-temperature filling up to 165°C
– Vacuum-sealable; perfect for long shelf life, barrier protection, and pasteurized content
🔧 If unsure, we can help select the right material based on your use case.
2️⃣ Drum Dimensions or Bag Size
-
Please provide your drum diameter and height, or
-
Your existing liner bag’s outer diameter and height for reference.
This helps us tailor the liner to ensure a snug, wrinkle-free fit inside your barrels or containers.
3️⃣ Filling Temperature
-
What is the maximum temperature of the liquid you will fill into the bags?
This is critical for choosing the right material and sealing method.
-
≤80°C → LDPE is usually sufficient
-
Up to 165°C → Aluminum barrier liner is recommended
❓ Additional FAQ Based on This Information
1. What material should I choose for high-temperature or pasteurized products?
If you are filling hot liquids (up to 165°C) or require vacuum sealing, we recommend our aluminum foil structure: PA/AL/PA/PP, which provides high barrier protection and withstands high heat.
2. Can I use LDPE liners for chemical or food applications?
Yes. Our clear LDPE liners are available in both standard and anti-static forms, making them suitable for food ingredients, powders, or general industrial materials at temperatures below 80°C.
3. How do I know what size liner I need?
Just provide your drum’s diameter and height, or the dimensions of your current liner. We will calculate the proper bag size with appropriate expansion and fit margins.
4. Do you offer anti-static drum liner bags?
Yes. For applications involving powder filling, electronics, or static-sensitive materials, we provide anti-static LDPE round bottom liners upon request.
