Custom Kraft Paper Plastic Composite Bag

 

A Custom Kraft Paper Plastic Composite Bag is basically a hybrid packaging solution that combines the natural look and feel of kraft paper with the durability and functional benefits of plastic. It's widely used for packaging everything from food items to promotional goods because it offers both visual appeal and practical performance.

 

The Custom Kraft Paper Plastic Composite Bag is made by laminating kraft paper (often 80–150 gsm) with a thin layer of plastic film (usually PE, PP, or PET). The plastic can be on the inside, outside, or in between layers of paper, depending on the intended use.
 

 

The typical layer structure of Custom Kraft Paper Plastic Composite Bag follows a "sandwich" design, with common configurations including:

•  Kraft Paper + Plastic Film (2-layer): The most basic type. Kraft paper forms the outer layer (for rigidity and printability), while plastic (e.g., PE, PP) forms the inner layer (for moisture/leak resistance).
• Kraft Paper + Middle Barrier Layer + Plastic Film (3-layer): For enhanced protection. A middle layer (e.g., aluminum foil, EVOH) is added to block oxygen, light, or odors-critical for perishable goods.

- Size and Capacity

•  Ranges from small pouches (e.g., 50g for spices, tea) to large sacks (e.g., 25kg for rice, fertilizer).

• Custom dimensions (length, width, gusset-side folds that expand capacity) ensure a snug fit for contents, reducing wasted space and transportation costs.

- Closure Types

•  Heat Seal: Permanent seal for one-time use (e.g., snack bags).
•  Zipper Seal: Reusable (e.g., coffee, pet food) to preserve freshness after opening.
•  Tie Handle: For easy carrying (e.g., gift bags, retail items like nuts or candies).
•  Valve Closure: For powdered/granular products (e.g., cement, protein powder) to allow filling without air trapped inside.
   

- Printing and Branding

•  Design: Full-color printing, matte/glossy finishes, or embossing (for a 3D texture) to highlight logos, ingredients, or sustainability claims (e.g., "Recyclable" or "Biodegradable").
•  Regulatory Compliance: Customizable to include mandatory labels (e.g., nutrition facts, expiry dates, safety warnings for chemicals).
   

- Additional Features 

•  Window: A clear plastic window (e.g., PET) to display the product (ideal for snacks, bakery items, or crafts).
•  Tear Notches: Pre-cut notches for easy opening (avoids the need for scissors).
•  UV Coating: Adds a protective layer to prevent ink fading from sunlight (useful for products stored outdoors, like gardening supplies).
•  Anti-Static Coating: For electronic components or chemicals sensitive to static electricity.
