Quad Seal Pouch

Comparison with Common Three-Sided Bag

What Materials and Techniques Are Used for Quad Seal Pouch?

1. Common materials:

Various composite materials can be used according to product requirements.

• Standard type: BOPP/CPP, PET/PE, suitable for lightweight products with low barrier requirements.

• High barrier type: PET/AL/PE, PET/VMPET/PE, suitable for products sensitive to oxygen and moisture.

• Abrasion-resistant type: PA (nylon)/PE, suitable for products with sharp edges or hardness.

2.  Manufacturing process:

Use a four-side sealing bag machine, completing the heat sealing of four sides at one time or step by step. The process is more complex than the three-side sealing bag but simpler than the flat bottom bag.

What Are the Applications of Quad Seal Pouches?

The application of four-sided sealing bags is very extensive, and it is particularly suitable for the following situations:

• Pet food: The standard packaging for dry pet food (cat food, dog food), as it is sturdy and durable, capable of withstanding the pet's scratching and the weight of the contents.

• Food: Coffee beans, rice, pasta, snacks, frozen food.

• Industrial products: Chemicals, fertilizers, building materials, lubricants.

• Daily chemical products: Laundry detergent, cleaning agents.

• Any product requiring the best printing effect: Because its two separate large printing surfaces are ideal canvases for brand display.

What Are the Advantages and Challenges of Quad Seal Pouches?

Advantages:

• Unparalleled printing effect: It provides the greatest creative freedom and the best presentation effect for brand design.

• Excellent product protection: Comprehensive sealing and sturdy structure offer top-level protection.

• Strong shelf appeal: The smooth and stiff appearance conveys a sense of professionalism and high quality.

• Anti-counterfeiting feature: Once opened, the edge sealing is damaged and difficult to restore, providing a certain anti-counterfeiting function.

Challenge:

• Inability to stand independently: This is the main difference between it and the self-supporting bag. It cannot stand on the shelf unless the contents can support it.

• Lower material utilization rate: Compared to the three-side sealed bag, a wider roll of film material is required to produce bags of the same size.

• Cost: It is more expensive than the three-side sealed and back-sealed bags, but usually lower than the flat bottom bag.
