1. Special Embossed Surface: Embossed vacuum bags feature a variety of special textured surfaces. When the embossed vacuum bag is evacuated, the patterns on its surface can create many micro-channels. Compared to vacuum bags without embossing, these micro-channels facilitate the smooth expulsion of air, making the vacuuming process more efficient. Moreover, this pattern design enhances the structural strength of the bag, making it less likely to rupture under external pressure or compression.
2. Improved Oxygen Barrier: Due to its textured design, embossed vacuum bags provide a higher oxygen barrier than ordinary vacuum bags, significantly extending the shelf life and flavor of food products while greatly reducing the incidence of freezer burn and moisture loss, thus reducing waste.
3. Material Composition: Embossed vacuum bags typically consist of two layers of material, with the inner layer being food-grade polyethylene and the outer layer being nylon, with a total smooth surface thickness of 80 micrometers.
4. Temperature Applicability: These vacuum bags can be used in a temperature range of -20°C to 100°C and are suitable for both indoor and outdoor vacuum packaging machines.
5. Enhanced Thickness and Durability: Embossing not only improves air flow but also increases the thickness of the bag, making it more durable.
6. Suitable for a Wide Range of Food Packaging: Embossed vacuum bags are suitable for packaging products that require high puncture resistance, such as meat with bones, while maintaining shape, flavor, and extending shelf life.
7. In Terms of Appearance: Transparent embossed vacuum bags provide good gloss and transparency for food packaging, which not only helps to protect the food but also enhances the visual effect of the product.
8. Environmentally Friendly and Food Safe: Some embossed vacuum bags are BPA-free and comply with food-grade standards, ensuring they do not contaminate food when heated.
