The DuPont Paper Bag is a hand-held bag made from the patented material Tyvek® (Tevyok®) produced by the American DuPont Company. It is essentially 100% high-density polyethylene (HDPE) non-woven fabric, manufactured through DuPont's exclusive flash spinning process. It combines the stiffness of paper, the waterproofing of films, and the durability of woven fabric, making it an ideal choice for high-end eco-friendly packaging.
The common weights of Tyvek® are 50g/㎡, 70g/㎡, and 100g/㎡. The weight determines the strength and texture:
50–70g/㎡: Lightweight and soft, suitable for gift bags, sample bags, and exhibition promotional bags. It has a low cost and strong folding ability.
100g/㎡ and above: Thick and stiff, with better tear resistance. Suitable for high-end retail bags, heavy object packaging, and cross-border e-commerce bags. The load capacity can reach 5–8kg.
Note: Avoid blindly choosing high weights. Excess weight will increase transportation costs and reduce flexibility. When folding, it is prone to creases.
The bottom structure determines the load-bearing capacity.
Square bottom bag: Self-standing, highly stable, suitable for storing large items such as clothing and gift boxes. It is recommended to add thick patches at the bottom to enhance the load-bearing capacity.
Envelope bag: Without sides or bottom, lightweight and portable, suitable for storing documents and samples. The cost is the lowest, making it suitable for promotional activities.
Note: DuPont paper has strong toughness but average puncture resistance. For items with sharp edges, an inner liner or hard cardboard reinforcement is required.
Hole-punched rope handle: Mainly made of cotton rope / nylon rope, low cost, suitable for batch customization, but the hole positions are prone to tearing - it is necessary to reinforce the hole positions (metal air holes / thick pads), which is a key detail for customization.
One-piece molded handle: Directly cut the bag body to use as a handle, simple and elegant, suitable for lightweight items, with a load-bearing capacity of ≤ 3kg.
Webbing handle: Handmade with high strength, suitable for packaging heavy items. It is recommended to select a color-coordinated webbing to enhance the overall texture.
The height of the bag body is recommended to be 5–8 cm higher than the contents, leaving enough space to avoid tearing the bag opening when taking or placing items.
Printing Process: Adapts to the characteristics of Tyvek®, requires the use of specialized inks (such as UV inks, water-based inks) to ensure the patterns are durable and do not fade.
Avoid full-page dark printing: The white base of Tyvek® is prone to color transmission, and full-page dark printing will increase costs and affect flexibility.
Hot stamping / hot silvering: Suitable for logos and key text, enhancing the premium feel.
UV local varnish: Highlights brand identification, adds a three-dimensional effect, suitable for beauty and jewelry brands.
Waterproof coating: Optional, enhances water resistance, suitable for outdoor or fresh produce packaging, but slightly reduces printing adhesion, needs to be tested in advance.
Proofing Confirmation: It is essential to first produce a physical sample to confirm the material, size, printing color, and load-bearing effect, to avoid rework after mass production.
Minimum Order Quantity and Delivery Date: The minimum order quantity for Tyvek® material is relatively high. The regular MOQ is 500 pieces, with a delivery period of 15–20 days. Urgent orders require prior communication and will increase costs.
Packaging and Transportation: The finished products should be packaged in waterproof film-covered cartons to prevent moisture during transportation; flat folding for shipment to reduce creases and damage rates.
Refuse "low-price temptation": Most low-price DuPont paper bags are counterfeit products, with poor toughness and easily fading prints. It is recommended to request material samples for comparison.
Provide a detailed requirements list: including the purpose, load-bearing capacity, target market, and printed content, to facilitate the manufacturer in recommending the optimal solution.
