Paper Box Application

Paper boxes, also known as cartons, are versatile packaging solutions that are used in a wide range of industries.

In this article, we will explore some of the many applications of paper boxes.

Our paper boxes are made using eco-friendly materials and manufacturing processes, making them a sustainable packaging solution. We are committed to reducing our environmental impact and ensuring that our products are as green as possible.

Wide Range of Sizes

We offer a wide range of standard sizes for our paper boxes, and we can also provide custom sizes as per the specific requirements of our customers. This flexibility allows customers to choose the appropriate size for their product, reducing waste and improving efficiency.

Paper Box Manufacturing Process

1) Fell the trees: Use softwood trees (i.e., pine and fir trees) from sustainable and managed woodland;

2) Make the pulp: The wood chips are chemically cooked and broken into pulp. Special chemicals like sodium sulphate are added to increase the strength;

3) Corrugation: For corrugated cardboard, we use two pieces of paper or card called liners and a portion of fluted cardboard, which sits in between the liners. The rolls of paper is made from the dried pulp and fed through a corrugated roller, which flutes or ruffers the paper;

4) Cutting: Cut the card to size, depending on customers’ specific requirements.

5) Assembly: Depends on customers’ specific requirements. We may use flaps and slots, tape, or glue and stitching to finish the assembly.

Paper Box By Use

  • Paper Box for Storage or Moving
We often use chipboard (cardboard or corrugated board) to make such kind of paper boxes. The sturdiness of chipboard makes sure the paper box provides enough protection for goods inside and minimizes possible vibrations and impact during storage or moving.
