The overviews for Paper Plastic Composite Bag

The Kraft Paper Plastic Composite Bag is a high - performance packaging solution, meticulously crafted by combining the natural strength and eco - friendly appeal of kraft paper with the durability and moisture - resistance of plastic. This unique combination results in a bag that offers the best of both materials, making it suitable for a wide range of applications.

The outer layer is made of high - quality kraft paper, which provides a rustic and natural look. It is also tear - resistant to a certain extent, protecting the contents from minor external impacts and abrasions. The inner layer consists of a plastic film, usually polyethylene (PE) or other suitable plastic materials. This layer serves as a barrier against moisture, liquids, and gases, ensuring that the packaged products remain dry, fresh, and free from contamination.

Available in a variety of standard sizes to meet different packaging needs, ranging from small bags suitable for holding a few hundred grams of products to large industrial - sized bags capable of carrying up to 50 kilograms or more. Custom sizes can also be ordered according to specific requirements.

Compared to pure plastic bags, the Kraft Paper Plastic Composite Bag has a more environmentally friendly profile due to the use of kraft paper, which is a renewable resource. Although it still contains plastic, efforts are being made to develop more sustainable versions, such as using biodegradable or recyclable plastics, reducing the overall environmental impact.

The smooth surface of the paper outer layer allows for high - quality printing. Companies can print detailed product information, usage instructions, barcodes, and attractive designs on the bag, enhancing product visibility and brand recognition on the market.
