Article Structure
Introduction
Paper bags have always been a popular type of packaging in the packaging industry. What materials are used to make paper bags? What are the characteristics of these materials? As a paper bag-making machine manufacturer, Poseipack will use an article to popularize it for you.
At present, the following raw materials are mainly used to make paper bags
Kraft paper
White cardboard
Coated paper
Recycled Paper
Laminating paper
Kraft paper
The appearance of kraft paper is often yellow-brown, with a tough, thick, and tear-resistant texture. Its overall properties are somewhat similar to those of kraft leather, so it is called kraft paper. Using this kind of paper to make paper bags will also yield the same properties, such as thickness and tear resistance.
Kraft paper is divided into brown kraft paper and white kraft paper according to the production process.
Brown kraft paper: It is the most primitive kraft paper without any bleaching process. Most of the original wood pulp is brown, so it is called brown kraft paper. This kind of paper is strong and tough. Because the color is generally brown and the surface is rough, it is only suitable for printing simple patterns.
White kraft paper: White kraft paper is based on brown kraft paper with a bleaching process, so it is white. Because it is white, it supports more colorful printing effects; however, at the same time, the toughness will be reduced accordingly.
If you need a sturdy paper bag, then kraft paper is your best choice.
White cardboard
White cardboard is mostly made of 100% virgin wood pulp with high density, so the surface of white cardboard is very flat and smooth, which is very suitable for printing or custom crafts. The printed colors will be brighter, and it has good folding resistance, making it an excellent raw material for high-end printed paper bags. If you have a limited material budget and want to print in color, white cardboard is a very good choice.
Coated paper
This kind of paper is specially coated on the surface, and it is named after the early use of “copperplate printing” technology. Through the coating process, a smooth and delicate coating is formed on the surface of the paper, which significantly improves the printing effect. It is very suitable for paper bags that need large-area printing. If you need high-end printing effects, coated paper is the best choice.
Recycled Paper
As the name suggests, recycled paper is a kind of paper that is made by re-pulping and molding recycled waste paper (office waste paper, newspapers, etc.). This kind of paper has lower strength because it uses mixed pulp with different fiber densities, but it is outstandingly environmentally friendly.
Laminating Paper
Laminated paper is paper that has been coated on the base paper. The film can be a plastic (BOPP/PE) film or a biodegradable film (PLA). Laminated paper has powerful functions and can be waterproof and oil-proof. It is currently widely used in the packaging industry.
