Sandwich Paper: The Unsung Hero of Food Packaging

Types of Sandwich Paper

While sandwich paper is primarily known for its basic function of wrapping sandwiches, there are a few variations based on specific needs and preferences:

1. Traditional Sandwich Paper:

• This is the most common type, typically made from thin, translucent paper.
• Offers basic protection against moisture and dust.
• Ideal for general sandwich wrapping.

2. Waxed Sandwich Paper:

• Coated with a thin layer of wax for added moisture resistance.
• Suitable for oily or greasy sandwiches, such as those containing mayonnaise or butter.
• Provides better protection against sogginess.

3. Parchment Paper:

• Often confused with sandwich paper but has a higher heat tolerance.
• Can be used for both wrapping sandwiches and baking.
• Offers good moisture and grease resistance.

4. Printed Sandwich Paper:

• This type features designs or logos for branding purposes.
• Commonly used by restaurants or cafes to promote their business.

Production Process of Sandwich Paper

The production of sandwich paper involves several key steps:

1-Pulp Preparation:

Wood pulp is the primary raw material.

The pulp is processed to remove impurities and fibers are separated.

2-Paper Formation:

The pulp is spread onto a moving wire mesh to form a sheet.

Water is removed from the pulp to create a paper web.

3-Drying:

The paper web is dried to remove remaining moisture.

4-Calendering:

The paper is passed through a series of rollers to smooth the surface and improve its appearance.

5-Waxing (Optional):

For waxed sandwich paper, a thin layer of wax is applied to the paper.

6-Printing (Optional):

If required, designs or logos are printed on the paper.

7-Cutting and Packaging:

The paper is cut to the desired size and packaged for distribution.
