Slider Zip Lock Plastic Bags are a type of plastic packaging bag that uses a sliding mechanism for repeated opening and closing.  Their key distinguishing feature is the use of a sliding zipper closure at the bag opening, rather than traditional press-to-seal or single-use closures. These bags are typically made from multi-layer composite films, with the zipper system heat-sealed to the bag body to form a complete, sealed structural unit. In terms of packaging form, they belong to the category of reclosable flexible packaging, combining both sealing functionality and structural integrity, and are widely used in product systems that require consistent packaging and ease of use.

1. Clear Slider Zipper Structure

Custom Slider Zip Lock Plastic Bags utilize a slider zipper design, featuring an independent slider component at the bag opening to ensure stable opening and closing. The slider and zipper track are precisely matched, resulting in smooth operation and reducing the likelihood of malfunctions. The zipper material is PE, balancing flexibility and structural stability, suitable for repeated sliding. This structure offers a distinct visual identity, contributing to a consistent product packaging image.

2. Multi-layer Composite Bag Material Options

The bag material can be selected from various structural combinations such as PET/PE, PET/NY/PE, PET/NY/White PE, PET/VMPET/PE, OPP/VMPET/PE, etc., depending on packaging requirements. Different material layers can be adjusted in terms of thickness, barrier layer configuration, and printing compatibility, ensuring excellent structural integrity of the Slider Zip Lock Plastic Bags. Common composite thicknesses range from 70–150μm, meeting diverse packaging needs.

3. Highly Customizable Patterns and Printing

These products support customer-defined bag patterns and visual information layouts, compatible with gravure printing technology for multi-color graphics. The printing area and slider zipper position are structurally planned to avoid interfering with the zipper's operation. Through unified pattern layout and bag shape ratio design, Slider Zip Lock Plastic Bags maintain overall consistency on store shelves, suitable for long-term brand series packaging.

4. Flexible Bag Shape Options

Custom Slider Zip Lock Plastic Bags can be manufactured in various bag shapes, including flat bottom bags, three-side seal bags, and stand-up pouches. Bag dimensions can be customized based on product volume and packaging equipment parameters, with controllable width, height, and bottom gusset proportions. The zipper position can be adjusted according to the bag shape, ensuring the packaging maintains a stable unfolded state and improving the consistency of the finished product's appearance.

5. High Sealing and Zipper Matching Accuracy

The zipper system is designed to match the bag body's heat sealing process during production, ensuring a stable bond between the zipper and the composite film. Heat sealing strength parameters can be adjusted according0 to the material structure, with common sealing strengths reaching 15–25N/15mm. Slider zip lock plastic bags feature a clear division of function between the sealing area and the slider area, reducing structural stress concentration problems.

1. Coffee Roasting Factory

In the coffee roasting factory, Kraft Coffee Packaging is used to hold roasted and cooled coffee beans. In this stage, the packaging primarily serves the functions of product portioning and batch identification, facilitating subsequent warehousing and logistics management. The bag type and capacity can be matched to the production rhythm, making the packaging process more orderly.

2. Specialty Coffee Retail Stores

In specialty coffee retail stores, Kraft Coffee Packaging is used as the direct display packaging for the product. The information on the packaging surface displays the coffee's origin, roast level, and flavor description, allowing consumers to quickly identify the product. The bag structure maintains a good three-dimensional shape when displayed on shelves and counters.

3. E-commerce Warehousing and Fulfillment Centers

In e-commerce warehousing environments, Kraft Coffee Packaging needs to adapt to picking, packing, and transportation processes. Flat-bottomed bags or side-gusseted bags are more stable when stacked. Standardized packaging sizes help improve warehouse space utilization and reduce the risk of deformation during transportation.

4. Coffee Brand Subscription Delivery

In coffee subscription delivery services, Kraft Coffee Packaging is used for the packaging of products shipped periodically. The pull-tab opening and resealable structure make it easy for end-users to access the product multiple times. The packaging maintains its complete shape within the delivery box, helping to enhance the overall delivery experience.

5. Trade Shows and Brand Promotion Events

At industry trade shows or brand promotion events, Kraft Coffee Packaging is often used as packaging for display samples or tasting samples. Customized patterns and bag structures help strengthen brand recognition. The packaging volume is easy to carry and distribute, making it suitable for short-term promotional use.
