Frozen food packaging bags easy to appear the following questions, maybe useful to you!

In the actual production, frozen food bags easy to appear the following questions: 1. Bag of impact resistance performance is poor, in the process of transportation, loading and unloading, and shelf displays vulnerable to external force damage, appear easily torn bags, open bags phenomenon, not only influence the appearance of packaging products, also cannot have the effect of the packing itself should be at the same time. 2. Smooth of wrapping itself is not good, the production process of open sex is poorer, the production efficiency is low, it will also reduce the utilization of the packet, cause waste to the cost. 3. Bag heat sealing strength is not enough, heat sealing temperature too high heat sealing layer damage phenomenon, which reduces the protection performance of the packet, greatly reduces the shelf life of the content, make content to reach the corresponding guarantee. 4. Small bags peel strength between the layers, tensile force is not enough, poor mechanical properties of the packaging bags, causing delamination, packet bags will not be able to achieve proper bearing function, the protection of contents cannot play an effective role. 5. The cold resistance of quick-frozen food can not meet the requirements, in the case of low temperature, can't keep the material the performance of the original packing material is brittle, make packaging material mechanical strength drops, cause bags to crack and craze, more can't meet the contents of protection. 6. Bags easy tear mouth cannot effectively play, the effect of tear strength too big bags is not easy to open, tear strength is too small to cause packaging mechanical properties is reduced, so as to meet the humanized design, easy tear at the mouth of the packet at the same time also to complete the product protection. 7. Packaging performance of puncture, frozen frozen food is generally hard, especially fish, meat, contain bones and rigid objects, transport and storage products in the extrusion is easy to make bags worn out, make the damage bags sealing, thus frozen food packaging bags of puncture is very demanding.
