Dear friends from the food manufacturing industry, have you ever encountered these troublesome issues?
Have you ever experienced that the nuts and chips you produced are soft and not crispy just a few days after being delivered to the supermarket?
The coffee powder and dried meat were filled with fragrance when they were packaged. But after being placed on the shelves for two weeks, their aroma disappeared?
What's even more worrying is that customers return the products, file complaints about the shortened shelf life, and the brand reputation gradually deteriorates...Ordinary packaging fails to prevent oxygen from seeping in and cannot withstand transportation pressure. Food turns color, oxidizes, collapses, and leaks air - each of these issues is a "killer" for sales.Nitrogen-filled PE (polyethylene) composite packaging has been developed precisely to address these issues
In simple terms, it involves introducing a small amount of nitrogen into the PE film to create a stable and uniform micro-pore structure. It's not like inflating a bag; instead, it gives the film its own "gas regulation" ability - high oxygen resistance and anti-compression, providing dual protection.
The oxygen permeability of nitrogen-filled PE is more than 50% lower than that of ordinary PE. Oxygen cannot enter, thus preventing the spoilage of oils, the fading of pigments, and keeping dry goods crispy. Experiments have shown that the preserved time of peanuts in nitrogen-filled PE packaging is extended by 40% at room temperature!
Traditional packaging bags collapse under pressure. The nitrogen-filled PE material has a more flexible structure and good elasticity. Even when stacked and compressed, they are unlikely to deform or leak air - you no longer have to worry about turning into a "vacuum compression bag" when you reach the supermarket.
Nitrogen-filled PE does not require additional aluminum foil or EVOH layers (high barrier materials). The single-material structure is easier to recycle, aligning with the environmental trend. Moreover, the saved return loss expenses can help you save a considerable amount of money in a year.
If you are involved in the production of puffed foods, baked pastries, nut snacks, coffee and tea, it is recommended to immediately test nitrogen gas PE packaging.Start by testing one batch of a popular product, comparing the crispness, aroma retention days of the ordinary PE, and the sales data will speak for itself.
What does your customer value? The crunchy sound when opening the bag, or the sense of trust that the product remains fresh even after two weeks of storage? Nitrogen-coated PE is the key to helping you gain this trust.
