Blue plastic bags provide visual contrast for foreign material detection in food processing, meat packing and industrial applications. The distinctive blue colour stands out against most food products, making it easy to detect if bag fragments accidentally enter production lines. Made from strong HDPE and LDPE materials, these bags handle heavy loads and resist tears from sharp objects.

Available in flat bag and gusseted pallet bag formats to suit different applications from small product packaging to large pallet wrapping. The food-grade materials are suitable for direct contact with food products while maintaining strength for demanding industrial use. All sizes stocked in Sydney for fast Australian delivery.

7 sizes available from 460 x 355mm to 1900 x 1245mm, in HDPE and LDPE options. See the table below for details.

Why Blue for Food Safety+

Blue is the colour of choice for food processing packaging because it rarely occurs naturally in food products. If a piece of blue plastic accidentally enters a food product, it is highly visible against the background of meat, poultry, seafood, dairy and most other foods. This visibility is critical for both visual inspection and consumer safety.

Many food safety management systems and HACCP plans specify blue packaging materials for this reason. Using blue bags demonstrates a commitment to food safety and provides an additional layer of contamination prevention beyond physical barriers alone.

The consistent blue colour throughout the bag material ensures detection capability is maintained even if the bag tears or fragments. This is why food processors choose purpose-made blue bags rather than simply using any available coloured packaging.

HDPE vs LDPE Blue Bags+

HDPE (High-Density Polyethylene): Thinner, stiffer material that provides excellent moisture barrier properties. Good for lighter products and applications where a crisp, firm bag is preferred. More economical for high-volume use.

LDPE (Low-Density Polyethylene): Thicker, more flexible material with superior puncture and tear resistance. Better for heavy products, sharp objects and demanding applications where extra durability is required.

Both materials are food-grade and provide the same blue colour for detection purposes. Choose HDPE for lighter applications and LDPE for heavier or more demanding use.

Frequently Asked Questions
Why use blue bags in 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 used in meat, seafood and food manufacturing facilities.

Are these bags food safe?+

Yes. Both the HDPE and LDPE blue 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 where food safety is critical.

What is the difference between HDPE and LDPE?+

HDPE is thinner and stiffer, providing good moisture barrier at lower cost. LDPE is thicker and more flexible, with better puncture and tear resistance. Choose HDPE for lighter products and LDPE for heavy or sharp items. Both provide the same food-grade quality and blue colour.

Can I use these bags for freezer storage?+

Yes. Both HDPE and LDPE bags are suitable for cold storage and freezer applications. They remain flexible at low temperatures and maintain their strength and integrity. The bags will not become brittle or crack in normal commercial freezer conditions.

What is the pallet bag used for?+

The large gusseted pallet bag (1900 x 1245mm + 1195mm gusset) is used to cover and protect entire pallets of product. It fits over a standard pallet and can be secured at the base. This is used for dust protection, moisture barrier, and to maintain the blue colour-coding across bulk shipments.

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.
