Why HDPE for Industrial Packaging+

High-density polyethylene (HDPE) offers an excellent balance of strength, weight and cost for industrial packaging applications. The dense molecular structure provides superior tear resistance and moisture barrier properties compared to lower-density alternatives, while remaining thin and lightweight.

HDPE bags are stiffer than LDPE bags, which makes them easier to handle and position during packing. The material holds its shape well and resists stretching under load. This stiffness also means HDPE bags make a distinctive rustling sound, which can be useful for auditory confirmation during quality checks.

For applications requiring maximum strength or flexibility, consider LDPE alternatives. For most industrial and food processing applications where moisture barrier and tear resistance are priorities, HDPE provides the best value.

Natural vs Blue HDPE Bags+

Natural (Clear): Semi-transparent film allows contents visibility for inventory management and quality inspection. Suitable for general industrial applications where foreign body detection is not critical. More economical for high-volume use where colour is not required.

Blue: Coloured film enables easy detection of foreign material in food processing lines. If a piece of bag accidentally enters a food product, the blue colour stands out against most foods. Required by many food safety protocols and HACCP plans in meat, seafood and food manufacturing.

Both colours provide the same HDPE strength and barrier properties. Choose based on your application requirements: natural for general industrial use, blue for food processing and safety-critical applications.

Frequently Asked Questions
What is HDPE?+

HDPE stands for High-Density Polyethylene. It is a strong, lightweight plastic with excellent moisture barrier properties and tear resistance. HDPE is stiffer than LDPE (Low-Density Polyethylene) and is commonly used for industrial packaging, food containers and bottles.

Are these bags food safe?+

Yes. Both natural and blue HDPE bags are made from food-grade materials suitable for direct contact with food products. They are commonly used in meat processing, seafood packing and food manufacturing applications.

What is the difference between HDPE and LDPE?+

HDPE is stiffer with better moisture barrier properties, while LDPE is more flexible with better puncture resistance. HDPE is more economical for applications where rigidity and moisture protection are priorities. LDPE is better for heavy or sharp items requiring extra flexibility and durability.

Can I use these bags in a freezer?+

Yes. HDPE bags are suitable for cold storage and freezer applications. The material remains stable at low temperatures and maintains its strength and barrier properties. The bags will not become brittle or crack in normal commercial freezer conditions.

Why choose blue bags for food processing?+

Blue is used because it rarely occurs naturally in food products. If a piece of bag accidentally enters a food product, the blue colour stands out and can be easily detected by visual inspection. This is a food safety best practice required by many HACCP plans and food safety protocols.

How many bags are in a carton?+

Pack quantities range from 100 to 1,000 per carton depending on the size. Smaller bags come in higher quantities (up to 1,000), while larger bags come in smaller quantities (100-250). Check the specific product listing for exact pack quantities.
