With the continuous expansion of the scope of use of plastic packaging bags, designers believe that the design and production of plastic packaging bags must meet at least the following four basic requirements.
First, good wear resistance, easy to use repeatedly. The beautiful design attracts the attention of customers.
Second, good sealing, different packaged goods, there are also different requirements for the degree of sealing. However, under normal circumstances, the goods that need to be sealed are generally afraid of moisture, mold and other characteristics, so most industries generally have relatively high requirements for the sealing performance of packaging bags.
Third, good practicality, in the design and production of packaging bags, Hengxiang plastic bag manufacturers remind to fully consider the specific way of customer use, such as the use environment, commodity performance, transportation mode, storage environment, etc., in addition to considering whether it is food packaging, it is necessary to consider whether it is harmless to human health.
Fourth, good preservation, according to the use conditions of different users and different goods, choose the appropriate material and reasonable ratio, design and produce plastic bags suitable for different industries. For example, some plastic products are afraid of long-term direct sunlight, which has an adverse impact on the preservation of the product, and the industry can improve and develop in this regard.
