How To Choose High-Quality mailing Bags? Does The Thicker The Bag, The Better The Quality?

 

With the booming development of e-commerce, express packaging as an important part of product transportation, its quality directly affects the safety and integrity of the product. However, there are many types of mailing bag on the market, and how to choose high-quality courier bags has become the focus of attention for many businesses and consumers. In response to this issue, we will popularize relevant knowledge for everyone.

 

Raw materials are crucial

The material of a courier bag is one of the important factors in determining the quality of a courier bag. PE is a common material for express delivery bags, which has the characteristics of being odorless, excellent low temperature resistance, good glossiness, and good flexibility; PE material is extracted from petroleum without any further processing. Its characteristics are crystal clear and transparent without any impurities, and its physical properties are particularly good. This type of express bag made of PE material is also known as a brand new express mailer bag.

There is also a type of express bag on the market called half new material, which uses recycled materials as the raw material. The sources of recycled materials are quite mixed, mainly including waste from the production of mailing bags, household waste plastics, industrial plastics, etc. These plastic products are sorted after recycling, cut, melted at high temperatures, and processed into plastic particles. Half new material mailing bag may have an odor and its toughness are not as good as PE materials.

 

 

Sealing methods cannot be ignored

The sealing method directly affects the sealing and waterproofing of the shipping bags. There are designs such as self-adhesive seals and zipper seals. We commonly use self-adhesive seals, which need to ensure that the seal is firm and not easily torn off to ensure the safety of the product during transportation.

 

Printing quality is also important

Having a beautiful logo on the delivery bag can add points to the company's image. If it is necessary to print the company logo, address, and other information on the courier bag, the printing quality should be considered to ensure clarity, visibility, and non fading.

 

Methods for judging quality

How should we judge the quality of a delivery bag when we receive it? We need to use the following methods:

Smell: The stronger the smell of the polymail bags, the worse the material, so bags with a strong smell are harmful to the body.

Touch: The better the surface gloss of the bag, the purer the raw material and the higher the quality.

Pulling: used to test toughness, some envelope polymailer bag can be torn open like pieces of paper when pulled, resulting in poor quality. During the tearing process of a good mailing bag, even if the outer layer is torn, the inner layer will still stick together.

 

In summary, when choosing a courier bag, we do not necessarily have to choose a thicker one. We can choose the appropriate thickness based on our product type. Generally speaking, conventional thickness can meet the needs of most products. We should consider more about the materials, sealing methods, and printing quality of express delivery bags. I believe everyone will be more adept at choosing express bags, providing more reliable protection for product transportation.
