This design ensures that the bag offers both strength and resistance to moisture, making it an ideal packaging solution for products that require extra protection. The bag features a seamless bottom, which enhances its ability to hold heavy loads without the risk of splitting or leaking.

Kraft paper is a sustainable material that is recyclable and biodegradable, while the plastic liner adds an additional layer of protection, ensuring that the contents remain safe and secure. These bags come in various sizes and configurations, making them suitable for packaging a wide range of products, from dry food items like flour and sugar to agricultural seeds and chemical powders.

2. Key Features
Seam Bottom Construction:
The seam bottom design offers enhanced load-bearing strength, which prevents the bag from breaking or losing its shape when filled with heavy products. This feature is crucial for industries that require reliable and secure packaging, such as food packaging, agriculture, and chemicals.

Customizable Sizes and Configurations:
These bags can be manufactured in a variety of sizes to accommodate different product types and packaging needs. The flexibility in design makes them suitable for small consumer goods or large bulk materials. Additionally, companies can customize the bags with printed logos or branding for promotional purposes.

Plastic Liner for Added Protection:
The interior plastic lining provides an extra layer of defense against moisture, dust, and other environmental factors that could compromise the quality of the contents. This makes the bags ideal for products that need to be kept dry, such as flour, sugar, seeds, or chemicals.

3. Applications and Industries
The Seam Bottom Kraft Paper Plastic Liner Bag is widely used across various industries due to its versatility and reliability. Some of the common applications include:

Food Packaging:
These bags are commonly used in the food industry to package products such as flour, sugar, rice, powdered beverages, and other dry food items. The kraft paper exterior provides a natural, rustic look, while the plastic liner ensures that the food remains fresh and free from moisture.

Agriculture:
For agricultural applications, these bags are ideal for packaging seeds, fertilizers, and other agricultural products that require both strength and protection from the elements. The moisture-resistant liner ensures that the contents stay dry and safe during transportation and storage.

Industrial Packaging:

Seam Bottom Kraft Paper Plastic Liner Bag: The Ultimate Industrial Packaging Solution

In the demanding world of industrial packaging, finding a solution that seamlessly combines strength, protection, and sustainability is a constant challenge. The Seam Bottom Kraft Paper Plastic Liner Bag stands out as a premier answer to this challenge. This sophisticated composite bag is engineered for reliability, designed to safeguard a wide range of products across diverse industries from moisture, contamination, and handling stress. By integrating the robust, eco-friendly appeal of kraft paper with the impermeable security of a plastic liner, it offers a performance-oriented packaging choice for businesses that cannot compromise on quality.

Product Construction & Key Features

The superiority of this bag lies in its meticulous construction:

Durable Kraft Paper Outer Layer:

The outer shell is made from high-grammage kraft paper, renowned for its high tensile and tear strength. This provides exceptional resistance to abrasion, punctures, and bursting during transportation, stacking, and storage. Furthermore, kraft paper offers an excellent surface for high-quality printing, allowing for vibrant brand logos, handling instructions, and product information that enhance your market presence. It's natural, wood-pulp base also projects an image of environmental responsibility.

Integrated Plastic Liner (PE):

Inside the sturdy paper shell lies a continuous, seamless plastic liner, typically made from Polyethylene (PE). This liner acts as a formidable barrier against moisture, vapor, gases, and odors. It ensures that hygroscopic or sensitive contents remain dry, stable, and protected from environmental factors that could degrade their quality. For food, pharmaceutical, or high-purity chemical applications, food-grade PE liners are available to meet stringent safety and hygiene standards.

Revolutionary Seam Bottom Design:

Unlike traditional pinch-bottom bags, the seam bottom features a hot-melt sealed base with no overlapping folds or seams. This creates a flat, stable foundation that distributes weight evenly and dramatically increases the bag's load-bearing capacity. This design is critical for preventing seam failure and leaks, especially when packaging heavy, dense powders and granules. The result is a bag that is significantly less prone to breaking or leaking from the bottom, ensuring product integrity and reducing waste and spillage.

Primary Applications Across Industries

The versatile nature of the Seam Bottom Kraft Paper Plastic Liner Bag makes it indispensable in numerous sectors:

  1. Chemical & Fertilizer Industry: Ideal for packaging plastic pellets, masterbatch, chemical powders, dyes, and composite fertilizers. The liner prevents moisture absorption and caking, while the strong construction withstands the weight of dense materials.
  2. Food & Feed Industry: Perfect for pet food, flour, starch, sugar, grains, and food additives. The moisture-proof barrier maintains freshness and prevents spoilage, and the availability of food-grade liners ensures compliance with health regulations.
  3. Building Materials & Minerals: Excellently suited for cement, dry-mix mortar, gypsum powder, and mineral sands. The seam bottom construction is crucial for handling these heavy products without the risk of bottom blowouts.
  4. Pharmaceuticals & Specialty Chemicals: Used for packaging sensitive raw materials, intermediates, and powders that require a high barrier against humidity and contamination.
