Resealable Stand Up Pouches

What Are the Main Structure of Resealable Stand up Pouches?

Similar to ordinary stand up pouches, it usually adopts a multi-layer composite film structure to balance printing, protection and sealing performance:

• Outer layer: PET or BOPP, providing excellent printing surface, mechanical strength and wear resistance.

• Middle layer (barrier layer): AL (aluminum foil) or VMPET (aluminum-coated film) provides high barrier properties (oxygen barrier, moisture barrier, light protection); NY (nylon) provides good puncture resistance and toughness.

• Inner layer (heat sealing layer): PE or CPP, providing good heat sealing performance to ensure the firm sealing of the bag body's edge and pull tab areas.

Key point: Zipper or gusset usually gets firmly bonded to the inner material through heat pressing during the bag-making process.

Main Application of Resealable Stand up Pouches

The resealable stand up pouches have a wide range of applications, especially suitable for products that need to be used in multiple sessions:

1. Food industry:

• Snacks: potato chips, nuts, biscuits, popcorn (the largest application area).

• Dry goods: coffee beans/powder, tea, dried meat, preserved fruits.

• Pet food: dry food, snacks.

• Seasonings: milk powder, protein powder, sauces.

2. Daily care products:

• Laundry detergent, laundry beads, wipes, makeup pads.

3. Medicine and health supplements:

• Pills, powders, nutritional supplements.

What Are the Advantages and Challenges of the Resealable Stand-Up Pouch?

Advantages:

• Ultimate convenience: It perfectly addresses the problem that traditional packaging cannot be properly preserved once opened.

• Maintain product freshness: It effectively prevents the contents from getting damp, oxidized, or spoiled, thereby reducing waste.

• Enhance brand loyalty: The thoughtful design can significantly improve the user experience, thereby increasing the repeat purchase rate.

• Increase product value: Functionally stronger packaging can support higher product pricing.

• Marketing information carrier: The large printing space can be used to provide descriptions, recipes, or promotional information.

Challenge:

• Higher cost: Components such as zippers and suction tips, as well as more complex bag-making processes, will increase production costs.

• More complex structure: When designing, the compatibility between the zipper/suction tip and the bag body, the sealing reliability, and the filling method need to be comprehensively considered.

• Environmental issues: The use of multi-layer composite materials along with additional plastic components (such as zippers and suction tips) makes recycling more difficult. The industry is exploring the use of a single recyclable material (such as a full PE structure) to manufacture resealable bags.
