How 50um Bags Support Reliable Packaging+

The 50um thickness represents the standard duty option in the LDPE range. It provides enough material to handle items with edges, moderate weight, and handling during shipping without the cost of heavy duty options. Most manufacturing and distribution applications work well with this thickness.

With over 40 sizes including extra large options up to 1200 x 990mm, this range covers everything from small components to bulk items and equipment. Blue bags in selected sizes support food processing operations where visual detection matters. This comprehensive size selection simplifies purchasing across multiple departments.

The combination of good durability and reasonable cost makes 50um bags the default choice for operations that need more than basic protection. Products arrive at their destination protected, and the bags withstand the rigours of warehouse handling and transport.

When to Choose a Different Thickness+

Choose 35um bags for lighter items where economy is the priority. Move up to 75um or 100um when packaging heavy items, sharp-edged products, or when bags will undergo significant stress during handling. The 50um thickness handles most standard applications, but demanding conditions may benefit from heavier material.

Frequently Asked Questions
Are 50um bags food-safe?+

Yes. These bags are made from food-grade LDPE and are certified for direct food contact. They are suitable for packaging dry and fresh food items including meat, seafood and produce.

What are the blue bags for?+

Blue bags provide visual contrast against food products, making them easier to detect during quality control. If a bag accidentally enters the product stream, the blue colour stands out clearly. This is why blue bags are commonly used in food processing environments.

Can these bags be heat sealed?+

Yes. LDPE bags can be heat sealed using standard impulse or constant heat sealers. Adjust temperature settings to suit the 50um thickness for a secure closure.

How does 50um compare to other thicknesses?+

50um is the standard duty option, twice as thick as 25um economy bags. It provides good puncture resistance for items with edges while remaining cost-effective for high-volume use. For heavier or sharper items, consider 75um or 100um heavy duty bags.

Are these bags recyclable?+

Yes. LDPE bags are recyclable through soft plastics recycling programs such as REDcycle collection points at participating supermarkets. Check local recycling guidelines for your area.
