Plastic Zipper Pouches are plastic zipper bags with a press-to-seal structure. They are sealed and opened via a press-fit mechanism, meeting the flexible packaging needs of everyday goods, food, and industrial products. These bags are typically made of common composite film materials such as PET, PE, NY, and OPP to meet the requirements of barrier properties, stiffness, and transparency in various packaging applications. The zipper portion is mostly made of PE or PP, which has good heat-sealing compatibility with the bag body material, ensuring a stable seal during production. The press-to-seal design offers convenient opening and closing, reusability, and a visible seal, providing a user experience that is easy to open and reseal in various packaging scenarios. During processing, dry lamination, extrusion lamination, or multi-layer co-extrusion processes are commonly used, allowing for customized production in different thicknesses, sizes, and structural combinations, providing brands with more flexible packaging appearances and more stable content protection.

1. Strong Sealing Performance:

The Plastic Zipper Pouch employs a press-lock structure, with zippers typically made of PE or PP, offering excellent heat-sealing compatibility and maintaining a stable seal within a heat-sealing range of 110℃ to 130℃. Bag body materials such as PET/PE and PET/NY/PE, after lamination, achieve an oxygen permeability of approximately ≤1.0 cm³/m²·24h and a moisture permeability of ≤1.0 g/m²·24h, keeping the contents dry during storage. The sealing section, after mechanical compression, allows for multiple opening and closing, meeting the needs of frequent use.

2. High Barrier Properties:

Plastic Zipper Pouches using structures such as PET/VMPET/PE and OPP/VMPET/PE achieve high light and air barrier properties. The metallized coating of the VMPET layer provides excellent light blocking capabilities, reducing light transmittance to below 2%. The NY layer in this composite structure provides tear resistance, and the zipper section maintains consistent flatness after lamination with the bag body. High-barrier structures are suitable for contents requiring odor retention, thus extending the effective protection period of the packaging.

3. Structural Stability:

Plastic Zipper Pouches can be customized in thickness according to the density and filling volume of the contents, with standard bag thicknesses ranging from 60μm to 150μm. The PET layer provides stable stiffness, while the NY layer offers excellent puncture resistance, allowing the bag to maintain its overall shape under external forces. The peel strength of the multi-layer composite structure generally reaches ≥3.0N/15mm, maintaining good structural integrity during packaging, transportation, and shelving, and is less prone to cracking or delamination.

4. Good Transparency:

For products that need to display the contents, PET/PE or MDOPE/PE structures can be selected, giving the Plastic Zipper Pouch a high-definition transparent appearance. The PET layer has stable optical properties, allowing for a haze of less than 3%, suitable for visual display. The oriented structure of MDOPE material allows the bag to maintain optical clarity even with film weight reduction. The transparent appearance helps brands enhance shelf appeal and is particularly suitable for packaging lightweight retail goods.

5. Highly Customizable:

The Plastic Zipper Pouch supports full customization of size, thickness, structure, printing effects, and zipper configuration. The bag body can be printed with 8 or 10 colors, achieving high color registration accuracy. The zipper can be single-track, double-track, or reinforced, making the product suitable for different sealing strength requirements. Composite materials can be adjusted to PET/NY/White PE, etc., according to industry requirements to meet light-shielding and functional protection needs, facilitating brand differentiation.

1. Supermarket Retail Shelves:

Plastic Zipper Pouches are suitable for displaying nuts, candies, dried fruits, and lightweight snacks in supermarkets. Transparent or metallic structures can be selected according to product shape, and zippers allow for repeated opening and access by consumers. Different thicknesses accommodate various packaging capacities, ensuring products maintain a good appearance on shelves. The composite structure reduces the risk of moisture damage, extends the display and storage life of goods, and improves packaging stability at the retail end.

2. Food Processing Plants:

In food processing plants, Plastic Zipper Pouches are frequently used for small-package packaging of powdered and granular raw materials. The press-sealed design reduces material dispersion and facilitates daily measurement. PET/NY/PE or PET/VMPET/PE structures can be selected based on the characteristics of the contents, providing barrier properties suitable for industrial food management. Heat-sealing strength remains stable on the production line, reducing packaging breakage rates.

3. Coffee Roasting Studios:

Plastic Zipper Pouches are commonly used for packaging coffee beans or ground coffee, offering both rigidity and a tight seal. VMPET structures with high barrier properties can be used to reduce oxidation. The zipper design allows roasteries to reseal the packaging after repackaging, suitable for everyday bulk sales. Customized printing can showcase brand information, increasing brand recognition at the point of sale.

4. Pet Food Stores:

Plastic Zipper Pouches are ideal for pet food products such as freeze-dried meat chunks and small kibble. The composite material keeps the contents dry, ensuring packaging stability during storage. Pouch thickness can be adjusted to increase load-bearing capacity based on weight. The press-lock seal facilitates frequent feedings, increasing the packaging's reusability. Printing space can be used to display product specifications and usage information.

5. Beauty and Personal Care Stores:

Plastic Zipper Pouches are commonly used for personal care products such as face mask powders, bath salts, and trial-size kibble. The PET or NY composite structure provides the necessary rigidity and surface smoothness, maintaining a high-quality packaging appearance. The zipper keeps the contents sealed during daily use. The bag can be customized with various printing techniques to maintain visual appeal in beauty store displays.
