3 Things You should know about High Bulk PE Coated Raw Material Paper

Paper cups are widely used for serving hot and cold beverages in various industries such as food, beverage, and hospitality. They are lightweight, convenient, and eco-friendly alternatives to plastic cups. The paper used for making cups needs to be sturdy, water-resistant, and able to withstand high temperatures. PE coated raw material paper is one of the most popular choices for making paper cups.

What is High Bulk PE Coated Raw Material Paper?

High Bulk PE Coated Raw Material Paper is a type of paper that has a high bulk or thickness compared to regular paper. The bulk is achieved by adding chemical pulp or mechanical pulp to the paper during the manufacturing process. This type of paper has a higher opacity, better printability, and a softer texture than regular paper.

PE or Polyethylene is a thermoplastic polymer that is widely used for coating paper to make it water-resistant and durable. PE coated raw material paper is used for making various types of cups, including hot and cold beverage cups, ice cream cups, noodle cups, and popcorn cups. The PE coating also provides a barrier against grease and oil, making it suitable for food packaging.

Applications of High Bulk PE Coated Raw Material Paper:

1. Making Paper Cups:

High Bulk PE Coated Raw Material Paper is extensively used for making paper cups. The paper cup making process involves printing the desired design on the PE coated paper roll and then forming it into a cup shape using paper cup making machines. The PE coating on the paper provides a water-resistant barrier that prevents the liquid from leaking out of the cup. The high bulk of the paper provides insulation and keeps the beverage hot or cold for a longer duration.

2. Food Packaging:

PE coated paper cup sheet and PE coated paper cup fans are widely used for food packaging applications such as pizza boxes, sandwich wraps, and burger boxes. The PE coating provides a barrier against moisture, grease, and oil, keeping the food fresh and preventing it from sticking to the packaging.

3. Disposable Tableware:

PE coated paper is also used for making disposable tableware such as plates, bowls, and trays. The high bulk of the paper provides sturdiness and insulation, making it suitable for serving hot and cold food.

Production Process of High Bulk PE Coated Raw Material Paper:

The production process of High Bulk PE Coated Raw Material Paper involves the following steps:

1. Pulp Preparation:

The first step is to prepare the pulp. The pulp can be prepared by either the mechanical or chemical method. In the mechanical method, the wood is ground and refined to produce mechanical pulp, while in the chemical method, the wood chips are treated with chemicals to dissolve the lignin and produce chemical pulp. The pulp is then bleached to obtain a white color.

2. Papermaking:

The pulp is then mixed with water to form a slurry and fed onto a paper machine. The paper machine consists of a wire mesh that filters out the water from the pulp, leaving behind a wet paper sheet. The paper sheet is then passed through a series of rollers that press and dry the paper.

3. Coating:

The dried paper is then coated with PE to make it water-resistant. The coating is applied using a coater machine that evenly spreads the PE solution onto the paper. The paper is then passed through a dryer to evaporate the solvent and dry the PE coating.

4. Cutting and Packaging:

The final step is to cut the paper into the desired size and shape and pack it in rolls or sheets for transportation and storage.

In conclusion, High Bulk PE Coated Raw Material Paper is animportant raw material used for making paper cups, food packaging, and disposable tableware. Its high bulk and PE coating make it an ideal choice for these applications as it provides sturdiness, insulation, and a water-resistant barrier. The production process of High Bulk PE Coated Raw Material Paper involves preparing pulp, papermaking, coating, and cutting and packaging. This raw material is widely used in the food and beverage industry and is an eco-friendly alternative to plastic cups and packaging.

When choosing High Bulk PE Coated Raw Material Paper, it is essential to consider the quality of the paper, the thickness or bulk, and the strength of the PE coating. The paper should have good printability and be compatible with the paper cup making machines. The PE coating should be of high quality and thickness to provide adequate water resistance and barrier against grease and oil. The strength of the PE coating should be such that it does not crack or peel off during transportation or use.

High Bulk PE Coated Raw Material Paper is available in various grades, depending on the application. The grade of the paper determines the thickness, strength, and water resistance of the paper. For instance, paper used for making hot beverage cups requires a higher grade paper with thicker PE coating to withstand high temperatures and prevent leakage.

In conclusion, High Bulk PE Coated Raw Material Paper is a versatile and eco-friendly raw material used in various applications in the food and beverage industry. Its high bulk and PE coating provide sturdiness, insulation, and a water-resistant barrier that makes it ideal for paper cup making, food packaging, and disposable tableware. When choosing this raw material, it is essential to consider the quality, thickness, and strength of the paper and the PE coating to ensure its suitability for the intended application.
