[Chinese Packaging Network News] According to experts from Chinese Packaging Network, the majority of courier bags currently available on the market are made from recyclable PE (polyethylene) materials. These bags are lightweight, cost-effective, and ideal for everyday use. However, there are also higher-quality courier bags on the market that come at a premium price. When shopping for courier bags, consumers should pay attention to several key factors to ensure they choose the best option for their needs.
First, the material's toughness is crucial. Courier bags made entirely from PE or new materials tend to be very durable and resistant to wear, offering excellent protection for the items inside.
Second, the thickness of the bag plays an important role in its strength. Since the density of PE and new materials is fixed, the thickness depends on the size and weight of the package. Typically, a thickness between 11-15 microns is sufficient for most deliveries. The thicker the bag, the more expensive it tends to be. It’s important to choose a thickness that matches the weight and nature of your shipment.
Third, the edge strength of the bag is essential. Many bags fail due to poor quality materials or substandard sealing techniques, leading to weak seams that can easily tear during transit. Always opt for courier bags with strong, well-sealed edges to ensure the safety of your packages.
Fourth, the adhesive used for sealing should be strong and suitable for the material of the bag. High-quality adhesives provide a secure, tamper-resistant seal. Water-based glues are commonly used and offer good stickiness and durability.
Fifth, the surface of the bag should be sticky enough to work well with courier labels. If the material contains impurities, it may not stick properly. Choosing all-PE or new materials ensures better adhesion and reliability.
Lastly, opacity is another important feature. A non-transparent bag helps protect the privacy of the contents and prevents unwanted visibility during transport.
Experts from Chinese Packaging Network advise that while cheaper, basic courier bags are suitable for lighter items like clothing, they may not be ideal for heavier or more delicate products. For such cases, it's recommended to use a combination of tape and a stronger, thicker bag or one made from new materials to ensure safe delivery. Always consider the nature of your shipment and select the right packaging accordingly.
