How to Pick PE Coated Paper Roll for Food Packaging?

When it comes to food packaging, choosing the right PE coated paper roll is important because it affects food safety, how well the food is preserved, and how the product looks. There is a growing need for safe and high-quality food packaging, so learning how to choose the right PE coated paper rolls is important for businesses in the food sector.  

Know Food Contact Safety Standards  

When it comes to food packaging, it is necessary to meet the international food contact safety regulations. This is especially important for PE coated paper rolls because these should have relevant certifications to ensure that no harmful substances are absorbed by the food. Additionally, the coated material should be food-grade safe PE to avoid inferior coatings that are unsafe for food contact. Ideally, choose products from accredited institutions to ensure certification to international food safety standards.

Evaluate Coating Thickness and Uniformity

The thickness of coatings affects how PE coated paper rolls work. If a coating is too thin, a roll may not have enough PE to function. If a coating is too thick, a roll will cost more money and be less flexible to process. Uniform coatings prevent problems like inconsistent moisture retention and leakage of oil. Uniformity can be evaluated by visually assessing the surface of the coating for spots and unevenness which are distractions of coating quality.  

Consider Barrier Properties

PE coated paper rolls provide a defensive shield to food by blocking moisture and oil, oxygen, and whatever else is outside. Different foods require different blocking (barrier) strengths. For example, fried food needs to be kept away from oil, and fresh foods need to be kept away from moisture. Evaluate how the paper resists water, oil, and gas to make sure it meets the needs of the food to be packed so it can improve shelf life and keep food fresh.

Determine How They Align With Processing Techniques  

Food packaging involves several steps like printing, cutting, folding, and sealing. So, when you choose a PE coated paper roll, it needs to align with these steps. It also needs to be of high enough quality to produce legible and lasting prints. Plus, it needs to be durable enough to resist cracking or peeling when it is cut and folded. As for the heat sealed packaging, it is important that the paper performs well enough under heat and sealing conditions to provide a tight seal.  

Assess the Bonding of the Coating to the Base Paper  

The PE coating and the base paper must be bonded well to ensure the pack retains its protective quality. Loose coating that peels away exposing the paper can lead to contamination and the loss of the pack’s integrity. You can rub the surface or bend the paper to test it. Good adhesion is indicated by coating that does not peel off. It also makes sure that the paper retains its structure when it is used in various conditions.

Include the Environmental Impact

More people want to use eco-friendly packaging options. To minimize ecological footprints, use recyclable or biodegradable PE coated paper rolls. Use eco-friendly production processes with sustainably sourced raw materials. This satisfies the needs of environmentally conscious consumers while allowing the company to meet their social obligations. 

Fit to Particular Food Packaging Requirements

Different varieties of food have distinct needs when it comes to packaging. For instance, frozen food needs PE coated paper rolls that can maintain pliability at low temperatures while microwave food needs heat resistant materials. When making the selection take into account the food’s storage conditions, shelf life, and use.
