What Is The Process Of Paper Converting?
The purpose of the converting industry is to transform or convert raw materials into finished products in different shapes and sizes for various applications. There are several types of converting processes, including paper converting, film converting, textile converting, plastic converting, and metal converting.
Paper converting is one of the most critical converting types, referring to transforming large rolls of paper into smaller shapes or sizes for a wide range of applications, such as boxes, bags, envelopes, labels, newspapers, and more. The equipment used in paper converting is called a paper converter.
How does a paper converter work?
- Unwinding
Paper is usually produced into large continuous rolls, so before converting, these rolls of paper should be unwound from the core and fed into the converter.
- Cutting
The cutting process includes roll slitting, sheeting, trimming, and more. By slitting and sheeting, rolls of paper are cut into the required specifications.
- Printing
Generally, there are three printing methods, flexographic, offset, and digital. The printing process includes adding design elements such as logos, text, and images to the paper and is often used to print corrugated containers, food wrappers, and disposable cups, just to name a few. Flexographic printing is ideal for custom printing.
- Folding and gluing
If finished products require folding, the paper is then fed into the folding equipment. Folds are created and glued together.
- Laminating and coating
Laminating and coating can strengthen the paper, enhance its appearance, and make it more durable.
