Introduction of Greaseproof Paper

In a broad sense, it refers to paper that can prevent oil absorption and penetration. In a narrow sense, it refers to a type of paper made from the bleached, semi-bleached, or unbleached chemical wood pulp through high beating degree treatment. It also includes paper grades that can resist the penetration and absorption of fats and oils produced by adding an oil repellent to the pulp or coating the surface.

 

Characteristic of greaseproof paper

The quantitative of the product can be as low as 20g/m2, depending on user requirements. It has a certain strength and high smoothness, but low air permeability. Due to the strong beating effect of the fibers, this paper has a lot of fiber bonding points, the porosity of the paper is very low, and the transparency is high. Therefore, the penetration and absorption of grease can be prevented.

After the high-viscosity beating of chemical wood pulp, it is copied on a Fourdrinier paper machine or is made by coating and processing with oil-resistant paint (casein type, varnish type, hot melt or resin type, silicate type).

It is widely used in the packaging of hamburgers, baked bread, biscuits, and other foods, and other oily items.

 

Introduction of Greaseproof Paper

 

Prospects of greaseproof paper

1. Vigorously develop paper-based packaging printed matter

Focus on the development of low-weight, high-strength, lightweight high-end packaging paper, and folding cartons, and develop in the direction of gifting and colorization. Firstly, paper product packaging based on folding cartons will have a larger development space, and secondly, the application of multilayer cardboard composite materials will become more and more extensive.

2. Vigorously develop paper-plastic packaging

Paper and plastic are the two most widely used materials in the packaging and printing industry and will coexist for a long time. In many fields such as food, medicine, health products, dairy products, cosmetics, and detergents, paper packaging is playing an increasingly important role.

3. Non-polluting green packaging is receiving more and more attention from society

How do microwave popcorn bags work?

  Microwave popcorn   has become a beloved snack for its convenience and deliciousness. Have you ever wondered about the science behind those magical microwave popcorn bags? In this article, we delve into the intricate workings of these bags, unraveling the secrets that make them pop with flavor. The Ingenious Design of Microwave Popcorn Bags Microwave-Safe Materials One crucial aspect of  microwave popcorn bags  is the use of microwave-safe materials. Manufacturers employ a combination of paper, polymer, and susceptor materials. The susceptor is a thin layer that contains a precise mix of materials to absorb microwaves, creating the ideal conditions for popcorn popping. Susceptor Magic The susceptor layer is where the magic happens. Composed of a metallic material like aluminum, it absorbs microwaves, heating up rapidly. This intense localized heat then transfers to the popcorn kernels, causing them to pop. The susceptor plays a pivotal role in ensuring uniform...

How to make microwave popcorn easily?

Microwave popcorn   is easy to make. Just heat microwave popcorn in the microwave for a few minutes and you will have hot popcorn. The main ingredient of microwave popcorn is fiber, not fried food, and less calories than regular snacks. 1. Remove the plastic outer packaging. Unroll the popcorn bag. 2.

Do not leave unattended. Continue to listen. It takes 2 to 4 minutes to cook popcorn in the microwave (1 to 2 minutes for mini bags). 5. For best results, stop microwaving when popping slows to 2 to 3 seconds between pops. Do not overcook and popcorn may burn. 6. Handle hot bogs with care. Open the bag and pull at the top diagonally with the arrow. It is normal if a small amount of corn kernels do not pop.     Maximizing Flavor To maximize flavor, shake the contents of the bag before microwaving....
