- Product Details
Ⅰ.Features & Advantages
1. Extremely strong bend resistance
Through the physical support of high-basis-weight cardboard, it can effectively protect the contents from being creased, bent, or broken. This is highly important for customers with such requirements.
2. Environmental sustainability
Made of paper material, it can achieve complete recycling and circular reuse. It is highly aligned with the current global trend of plastic reduction bans and green logistics policies, greatly enhancing a brand’s eco-friendly image.
3. Space-saving and freight cost reduction
Compared with cartons, it is extremely flat and very lightweight. Compared with bubble mailers, it does not have a plastic air layer. For the same quantity, its storage volume is only a fraction of that of bubble mailers, greatly reducing warehousing and transportation costs.
4. High-quality surface texture
The paper surface is very smooth and flat. Whether for writing, stamping, or high-precision full-color printing on the surface, it can present excellent results. It is often used for business document delivery and gift packaging.
5. Waterproof and dustproof
The envelope surface can be laminated or coated, enabling the envelope to have certain moisture-proof and stain-resistant capabilities.
