Product Introduction
Want to give your product packaging a more premium feel, or need moisture-proof and dust-proof storage for your home? Laminated non-woven bags might be a great choice. They are made by adding a layer of PE film to ordinary non-woven fabric, making the bags more waterproof, more durable, and suitable for more attractive printed designs.

Suitable for |
|
Single-sided laminated bags |
Only a single film layer is applied to the outside of the bag, providing sufficient waterproofing at the most affordable cost. |
Everyday moisture-proof packaging, such as outer bags for ordinary goods, or as covers for clothing to protect against dust. |
|
Double-sided laminated bags |
Laminated inside and out, offering superior waterproofing and oil resistance, with a smooth surface for easy cleaning. |
For scenarios with high packaging requirements, such as carrying cooked food with liquids, fresh produce, or as tote bags for high-end gift boxes. |
|
Laminated printed bags |
High-definition printing is applied to the laminated layer, resulting in vibrant colors and extremely high image fidelity. |
For brand promotion, event distribution, and gift packaging, where the bag itself becomes a walking advertisement. |
|
Laminated 3D bags |
The laminated design combined with a square bottom allows the bag to stand stably on a table, enhancing its load-bearing capacity. |
For items that need to be displayed upright, such as gift boxes, shoe boxes, or packaging large quantities of fresh produce or takeout. |
|
Laminated zipper bags |
A built-in resealable zipper provides optimal protection against moisture, dust, and odors. |
For long-term storage, such as seasonal bedding and clothing, or tea and dried goods that need to be sealed for preservation. |
