1. With Flip Top Design (Reusable Opening and Closing)
The bag mouth is designed with a foldable "flip" part (usually an extension of the upper part of the bag body) for temporary sealing;
After the customer takes out the food, the bag mouth can be folded down and the flap can be covered to prevent dust, oil leakage, and odor diffusion;
The flap structure does not require glue or zippers, is low-cost, easy to operate, and meets the fast-paced retail scene.
2. Combined with the saddle hanger structure to improve operating efficiency
The center hanging hole is still retained and can be hung on the saddle bracket; the clerk can tear the bag with one hand and quickly flip the lid to seal it, so that the work can be smooth even during peak hours.
3. Bottom/side seal heat sealing, anti-leakage design
Mostly adopt bottom sealing or two-side edge sealing hot pressing, which is not easy to leak when carrying cooked food and food with oil and soup; some products use three-side sealing + flap design at the bottom to improve the overall load-bearing and durability.
4. Customized printing area includes flap surface
The flap can also be printed with brand logo, promotional information, food tips, etc.; enhance brand display space and customer visual impression.
5. Highly transparent or matte material combination
A transparent window can be designed on the front, and frosted or matte film can be used on the flap, with clear visual layers; it helps customers to directly identify the product before opening the bag.
6. Anti-slip and anti-adhesion treatment improves bag opening
Due to the complex structure of flap bags, embossing treatment or antistatic agent is often used to ensure that the bags are easy to separate and non-sticky; increase the convenience of use and reduce the situation of flap "stuck" or unsmooth operation.
