Nut bags sealing the cause of the rupture

Nut bags in the food packaging is a large category, seen bags are generally 3-side and self-reliance bags, it can be aerated pumping air into vacuum state, then burst nut bags in sealing, we take a look at the reason and solution. A composite membrane, the reason of packaging materials packaging bags are using the peel strength is poor, the composite film of each single layer film, the composite fastness difference between prone to composite membrane statified phenomenon, when hot pincer-like device of high heat sealing strength, under the impact of the packaging contents or from external extrusion, hot pincer-like device easy happening layered composite membrane, lead to leak and rupture occurred near the heat seal packing. By blasting stress ( Positive pressure method) Validated, peel strength test. Second, the production process of hidden trouble of jorge sealing equipment parameter Settings, easy to heat seal the heat sealing of poor quality, poor heat sealing ( The heat sealing is not tight, easy separation) Excessive (or heat sealing The heat seal strength is too big, appear heat seal root fracture) The phenomenon, easy cause heat seal leak and rupture. By sealing performance ( Negative pressure method) Validated, heat sealing strength. Due to the particularity of nuts food packaging bags, in the production of nuts, food packaging bags, both process and material, the thickness of the material or heat sealing method, will be a special treatment. In bags of product testing, we are usually on the strength of the material, sealing there will be a strict examination, to ensure good product quality with nuts, food packaging bags. Nuts, packaging bags, packaging manufacturers, nut bags, dried fruit bag.
