1. Product Composition and Design
The White Paper Plastic Composite Middle Seam Bag is composed of a layer of white paper combined with a plastic film, typically polyethylene or polypropylene. The middle seam design enhances the bag's strength and stability, making it suitable for both light and heavy-duty applications.
Paper Layer: The outer layer is made of high-quality white kraft paper, known for its nice tensile strength, tear resistance, and natural appearance. This provides the bag with a sturdy and robust exterior.
Plastic Layer: The inner layer consists of a plastic film that acts as a moisture barrier, protecting the contents from humidity, dust, and other external elements.
Middle Seam Design: The middle seam design is a key feature that increases the bag’s load-bearing capacity. It provides a smooth and uniform seal, improving its durability and resistance to tearing or puncturing under pressure.
Advantages
The White Paper Plastic Composite Middle Seam Bag offers several advantages over traditional paper or plastic bags:
1. Durability and Strength: The combination of paper and plastic ensures a high level of durability, making it ideal for packaging a wide variety of products, from bulk chemicals to food ingredients.
Tear-Resistant: The paper layer provides robust protection against tears and punctures, while the plastic layer enhances its overall strength.
Load-Bearing Capacity: The middle seam design contributes to a higher weight capacity, allowing the bag to carry heavier loads without compromising its structural integrity.
2. Moisture Protection: The plastic layer acts as a moisture barrier, preventing the ingress of water, which is crucial when packaging sensitive materials such as flour, fertilizers, or chemicals.
Water-resistant: Protects the contents from rain or humidity during storage or transportation.
Longer Shelf Life: The moisture barrier helps extend the shelf life of the products inside, especially for food and agricultural goods.
