Packaging is easy to broken bag? Source factory suggest you to do so

Mall, there are many exquisite packaging, but some problems easily broken bag bag, whether it's clothing bags, food bags, aluminum foil bags, composite bags, cosmetic bags, hardware bags, retort pouch, such problems are more or less. But few professional manufacturer of flexible packaging packaging customer response to this problem, today, combined with their own produce experience, how to interpret for you reduced packaging bag broken rate. 1, quality problem analysis some bags in the process of transporting and selling, the bag body surface, Athermal pincer-like device) Torn bags. 2, 1 quality problems cause analysis. Packaging material penetration resistance is poorer some products with sharp edges, such as hardware products, cosmetics, etc. , these products will have a certain piercing force on packing bag, if the bags penetration resistance is poorer, is likely to happen to break the bag. By testing the puncture resistance, sealing performance ( Negative pressure method) Two indicators. 2. Grease resistance is poor in some packaging materials products grease composition is higher, if the oil resistance of packaging materials, poor contact grease composition for a long time, easy to cause the flexibility, penetration resistance drop, easily torn bags problems. Such as packing the packing bag of melon seeds benevolence and not packing the packing bag of melon seeds benevolence of tensile force, craze elongation ( These two indicators through tensile & middot; Elongation and modulus of elasticity test) Large difference. 3. Flexible packaging materials if packaging flexibility is poor, poor brittleness is big, easy under the impact of the internal product or external impact effect under the torn bags. Can pass the test of tensile & middot; Elongation and elastic modulus, pendulum impact energy these two indicators for validation. 3, packet source factory advice to focus on the packaging of the puncture resistance, pendulum impact energy, peel strength, tensile & bull of packaging film; Elongation and elastic modulus, products packaging of tensile & middot; Elongation and elastic modulus, sealing function ( Negative pressure method) Such as the performance of routine monitoring. Flexibility, grease resistance and puncture resistance excellent packaging materials, or by increasing the thickness of the measures to the existing packaging material penetration resistance, oil resistance and other performance improvements.
