For manufacturers or stores that just contact plastic packaging, it is a headache for them to identify whether their customized plastic bags are qualified. If we can't identify the cat bags in plastic bags, they will easily be fooled by some unscrupulous businesses. Small plastic bags can also damage the image of your brand. Shanghai Rui is committed to build Shanghai plastic bag integrity brand, for your corporate image escort. Now give you a few tips:
1. first look at the appearance, the normal plastic bags, plastic packaging should be uniform color, whether it is natural or milk white. If the color is not uniform, there is a large color difference or turbidity, you should be careful, it may not be made of pure raw material.
2. smell method, normal plastic bags will not have any peculiar smell. If you get the smell and odour of the products, it also means that bad filler is added, which may have a bad effect on your products, especially food bags. The consequences are especially serious. Before I heard that there was a colleague because of the peculiar smell of the bag, which caused all the food in the customer to be contaminated, and eventually lost millions of yuan.
3. strength test, get the plastic bag of the hand, first cross the rip and tear it longitudinally, check the transverse and longitudinal strength of the bag, or directly install your product, try to check whether the bottom seal is reliable and whether it is hot or not.
4., print quality check. First, compare the color of the product with the color you want, whether there is a big color difference, then check the color matching between different colors.
In addition, it is necessary to remind you that the normal use of plastic bags is non-toxic. If you use inferior plastic bags for high temperature food, there may be toxic substances released. Long-term consumption will be harmful to health. For your health and environmental protection, please refuse to use a poor plastic bag or a super thin plastic bag.
