What is Plain Doypack? Flat Doypack Packaging Advantages

One of the most practical solutions in the flexible packaging industry, Flat Doypack is a type of packaging that takes its name from its completely flat structure with no bottom bellows and its three sides are factory-sealed. This system, also known as "3 Side Seal Pouch" in the technical literature, offers the highest sealing and protection performance, especially for products that are displayed on shelves or portioned inside the package.

Design of Flat Doypack Packaging and Efficiency

Flat Doypack models have a simple and functional design, far from complex forms. These bags, whose two vertical edges and bottom part are sealed by heat treatment, provide full protection by sealing from the top after filling. This simple structure minimizes costs while increasing the production speed of the packaging. In particular, allowing printing on both surfaces of the product creates a wide graphic display area for brands.

Why Should Plain Doypack Be Preferred? (Basic Advantages)

We can collect the main reasons for choosing these flat form packages under the following headings:

1. The Most Economical Packaging Solution: It is the flexible packaging type with the lowest unit cost because it does not have structures that require additional materials such as bottom bellows or side bellows. It offers a budget-friendly solution for high volume production.

2. Maximum Sealing and Protection: The solid welded structure of three edges completely prevents air and moisture ingress. This provides the most reliable protection, especially for delicatessen or medical products that require vacuum packaging.

3. Storage and Logistics Ease: Thanks to its completely flat structure, it takes up minimum space in boxes and shelves. Being as thin as paper when empty, it significantly reduces transportation costs and warehouse space.

4. Suitable for Hanging Display: It is the most suitable model to be displayed on hanging stands of markets, thanks to the "Euro Hole" (Mexican Hat) holes that can be easily added to the upper part. This maximizes the visibility of the product in narrow areas such as the front of the cash register.
