In recent years, with the increasingly strict environmental protection policies and the rising public awareness of environmental protection, a lot of people have turned to use paper bags. Making paper bags is a great way to reduce the amount of waste that goes into landfills. Not only are they sturdy and can carry a lot, but they are also environmentally friendly. In this blog post, we will discuss the production process of eco-friendly paper bags. We will go over the different materials that are used, as well as the steps involved in making these bags. Let’s get started!
What are eco-friendly paper bags
Eco-Friendly paper bags mainly refers to the paper bags used in the production of materials relative to plastic bags that are more easily degradable in the environment, more friendly to the environment, the production process is also less polluting to the environment. Paper bag’s raw material is mainly paper, is produced from trees and other plants to get, is a renewable resource. They are often used as an alternative to plastic bags, which are not biodegradable. Which reduces the amount of waste produced, and helps to take care of the environment. Paper bags have been widely used in various aspects of life today, such as supermarket shopping, food packaging, gift packaging, etc.
The production process of eco-friendly paper bags
The production process of eco-friendly paper bags starts with the harvesting of trees. The wood from the trees is then chipped and pulped to create paper pulp. The paper pulp is then formed into sheets and dried. Once it is dry, it is cut into the desired shape and size. After that, it will be packaged into paper rolls, and then be used as raw material to produce paper bags.
Once we have the raw material, we will use paper bag making machine to make the paper bag that we need. Let’s take two examples to see the paper bag is how to make by paper bag machine.
The first example is using for making the paper bag without handles. All these production processes can be done by our semi-automatic square bottom paper bag making machine with high speed.
The second example is using for making the paper bag with handles inline. All these production processes can be done by our fully-automatic square bottom paper bag making machine with high speed.

Different materials that are used in making paper bags
Paper bags are mainly made of kraft paper, white cardboard, black cardboard, coated paper, glossy paper, medical paper, and special paper, etc.
Kraft paper: Kraft paper is also known as natural kraft paper. It has high tensile strength, high toughness, usually brownish yellow, high tear strength, rupture, and dynamic strength, widely used in shopping bags, food packaging bags, takeaway bags, etc. Commonly used thickness is 120 grams – 300 grams. Its price is relatively low.
White cardboard: White cardboard is firm and thick, with high straightness, breakage resistance, and smoothness, flat paper surface. Widely used in high-end custom gift packaging paper bags, exquisite shopping bags, etc. Commonly used thickness is 210 grams -300grams, the most used is 230 grams white cardboard. Paper bags printed on white cardboard, full color, paper texture is also very good.
Coated paper: Coated paper surface is very smooth and flat, high whiteness, high smoothness, good gloss, with good printing performance, printed graphics, and images with a three-dimensional feel. Its printing effect is the same as white cardboard, however, the stiffness is not better than it. Commonly used thickness is 128 grams -300 grams.
White kraft paper: White kraft paper is made from 100% pure wood pulp, environmental protection, non-toxic, environmentally friendly recycling, white kraft paper toughness is very good, high breakage resistance, uniformity thickness color image stability, excellent printing effect and do not need to laminate. Widely used in the production of environmentally friendly clothing tote bags, high-end shopping bags. Commonly used thickness is 100 grams -200 grams. However, White kraft paper is without brightness and gloss, it is not suitable for printing ink with too large content.
Laminated Paper: Laminated paper is a variety of kraft paper as the substrate, on top of the kraft paper will be hot melt PE plastic particles evenly coated on the surface of the paper laminated, thus forming a laminated paper, compared with ordinary paper, the laminated paper has the characteristics of waterproof, oil-proof, etc. It is very suitable for food packaging paper bags.
There are also many other materials to choose from in the production process of paper bags, such as coated paper, black cardboard. Each material has certain characteristics, we can choose the appropriate material according to our product type, product needs, or the type of paper applied to the paper bag making machine in order to produce a perfect and expected product.
The steps involved in making eco-friendly paper bags
In order to make it easier than you might think! we will outline the steps involved in making eco-friendly paper bags. Not only are they good for the environment, but they can also save you money! Let’s know how to do the paper bag more efficiently together.
Step 1. Need to clarify the expected type of paper bags to be produced, paper bag size
Step 2. Need to understand the production stages of paper bags, for example, whether to print, whether to make paper handles
Step 3. Need to determine what equipment can be used to make the expected paper bag
Step 4. Purchase the appropriate raw materials, such as paper roller, or paper sheet
Step 5. Arrange mass production
With the continuous implementation of the policy of plastic ban, as well as foreign countries, Europe and the United States and other countries to promote the trend of using environmentally friendly paper bags, strict control of plastic pollution, plastic bags will be replaced by environmentally friendly paper bags, the use of paper bags will become increasingly popular, people’s demand for paper bags will also be greater and greater. The future of the Eco-Friendly paper bags industry is still worth expecting.
