1、 How to identify flat pocket materials:
Although governments around the world are currently restricting the use of flat bags, plastic bags are still an indispensable necessity for retailers in business activities. In the current domestic market, it is still very common for businesses to customize plastic bags. So how can retailers identify the materials of customized plastic bags?
(1) High pressure bag and low pressure bag:
These two common commercial materials are both PE materials, but they have different characteristics. The former feels relatively soft, has a shiny exterior, and is relatively strong (resilient). Therefore, this material is often used in handbags and finished bags required for industrial packaging.
The application range of low-pressure bags is mainly in shopping malls, supermarkets, and the food industry. For example, low-pressure bags used in the kitchen of restaurants, as well as vest bags sold to consumers for compensation by supermarkets, are all made of this material. Its appearance is characterized by tensile resistance, and occasional tearing does not easily deform it. The hardness is also strong, and it is not easy to be pierced by blunt objects.
Both are made of PE, how do you distinguish between these two types of plastic bags? One of the simplest methods is to tear open the bag like a line of paper. If there is a white mark on the tear, it indicates that it is a low-pressure bag, and if there is no white mark, it is a high-pressure bag. If a merchant has both a low-pressure bag and a high-pressure bag in their hands, during this experiment, it will be apparent that the high-pressure bag will have greater resistance when it is pulled in.
(2) PP bag and OPP bag with the highest transparency
These two types of bags are the most transparent of all plastic bag materials, so they are often customized as packaging bags for clothing and gifts. The difference between the two is that the PP bag is relatively hard and has a smooth feel. When you shake it with your hand, it will make a loud noise. Generally, plastic bags do not leave any folding marks, but when folded in half, PP plastic bags will have a mark like a paper fold.
The transparency of OPP bags is also very high, but the difference is that OPP is more brittle, which is more prone to damage due to its brittleness. However, this damage is based on the fact that the material has already burst. Customized plastic bags made of this material can easily tear apart once there is a gap.
The above four materials are the most common flat pocket materials on the market at present, and the difference method is relatively simple.
