PE Coated kraft paper is safe for food

PE Coated kraft paper is safe for food contact and does not alter the taste or odor of foods. It is also sturdier than traditional paper.
During processing, the plastic film is heated and made into a 0.04cm thin layer on the surface of kraft paper. This makes the coating hard to strip off the paper.
Waterproof
The PE coating of kraft paper makes it water-resistant. This is one of the reasons why kraft papers are so durable and long-lasting, as they can be used for a very long time. Moreover, this coating also helps in keeping dry products dry and moist products moist against environmental differences. However, it is not very good at letting oxygen pass through.
Compared to uncoated paper, PE-coated paper has lower Cobb values, which means that it can hold less moisture. This is why it is a popular material for disposable food packaging containers, such as PE-coated paper cups.
This type of paper is also used for packaging metal products. It is waterproof, and provides extra protection from oils, water and grease. In addition, it has high tensile strength. Moreover, it is easy to handle and can withstand harsh environments. This is why it is ideal for industries such as aerospace, heavy equipment and transportation vehicles. In addition, it is an excellent choice for wrapping metal parts and tools.
Tear-Resistant
Unlike uncoated kraft paper, which gets soft when exposed to water and loses its shape, PE-coated kraft is resistant to moisture. The outer layer of PE prevents water from oozing out, and the inner layer keeps moisture away from the paper. This makes it the ideal choice for food packaging, especially if you plan to heat-seal it.
This type of paper is also used as a release liner for pressure-sensitive adhesives. The PE coating offers barrier properties and protects the adhesive from sticking to the surface of the paper. It is also a good choice for products that require moisture protection.
Aside from protecting the contents of your packages, this kind of paper is also environmentally friendly. It can be composted under certain conditions, and it has an excellent shelf life. In addition, it is available in sheets and rolls, making it easy to customize as needed. It can also be printed with high-quality graphics, including logos and images.
Heat Resistant
The PE coating prevents the paper from absorbing moisture and grease. It also offers barrier properties, which protect it against odors and microorganisms. This feature makes it ideal for food packaging and labeling applications. Additionally, the PE coating resists heat and is less prone to wrinkles.
The paper can be printed with high-quality branding information using offset printing. It is also a suitable material for use as a release liner for pressure-sensitive adhesives. Its blocking effect against migrating contaminants helps minimize problems caused by uncured silicone drips in the cover film printing process. Furthermore, it provides a low hygro expansion, which helps to improve the stability of composite films/paper laminates.
The kraft paper with PE coating is available in two types: single-sided and double-sided. The single-sided type is used as disposable paper food packaging bags. The outside of these bags will print the brand LOGO and relative information to get better promotion. The double-sided paper is typically used for making paper cups and to-go boxes.
Biodegradable
Unlike traditional kraft paper, which gets soft and out of shape when it meets water, PE-coated kraft papers are completely waterproof. This is because the plastic layer prevents liquids from directly contacting the paper. The resulting paper is extremely durable and can be printed on to create aesthetically appealing packaging for food products.
When used correctly, PE-coated papers are safe to use in food packaging. However, they must be handled carefully so that they don’t endanger the health of consumers or cause environmental pollution. To ensure this, manufacturers implement quality control measures and testing methods, as well as comply with industry standards and regulations.
