Identification packaging aluminum foil bag
Packaging aluminum foil bags are also called "anti-static aluminum foil bags" and "pure aluminum bags". They are opaque in appearance and silver-gray. Aluminum foil has good barrier properties, heat sealability, light shielding, high temperature resistance, low temperature resistance, oil resistance, fragrance retention, non-toxic, tasteless, softness and other characteristics. Products of different composite materials and thicknesses can be customized according to requirements, storage environment Temperature≤38 ℃, humidity≤90%. The identification of packaging aluminum foil bags is mainly considered from the following aspects.
Materials for packaging aluminum foil bags
When buying, you can first smell the odor. It does not meet the sanitary standards, and the second is that it may affect the normal use of the packaging aluminum foil bag. On the contrary, if there is no odor, you can check the transparency of the bag, whether the clarity is uniform, and whether there are impurities If it is difficult to tear, it means that the heat-sealing fastness is good. Otherwise, it is not good. However, the bags of different uses have different levels of firmness.
Whether the sealing of the packaging aluminum foil bag is secure
The fastness of the aluminum foil for packaging bag is mainly divided into two kinds of composite fastness and hot air fastness. The main identification method is to first see if there are several layers of structure at the crack, and then see if you can separate it by hand. The firmness is good, otherwise it is poor; so check the firmness of the bag and also check whether there are bubbles or wrinkles on the surface of the bag.
Neatness of the appearance of the packaging aluminum foil bag:
You must first observe the stiffness of the bag. Generally, the higher the flatness, the better, but it is not required due to the different materials. For example, a bag made of nylon and high-pressure film will have a wavy shape at the heat seal; you also need to observe the bag. Whether the cut edges are neat, the more neat the better.
Packaging aluminum foils bag printing quality:
You need to look at the printing quality of the packaging aluminum fois bag. The higher the level of realism of the physical map is, the better. If there is, it means that the printing requirements are not standard. See if there are drawing, fogging, blocking, and missing printing.
