Advantages of food-grade PE coated paper in food packaging

2025-11-18

As the core material of canned food packaging, food grade PE coated paper not only meets the basic requirements of "complying with standards", but also becomes an important support for brand professionalism and user experience through deep adaptation of material characteristics and product design. The size data you provide precisely maximizes the advantages of this material.
Essentially, the "dual structure" of food grade PE coated paper is the core guarantee. The outer layer of kraft paper or whiteboard paper provides structural support, while the inner layer of food grade polyethylene (PE) film forms a "stable barrier" - this film needs to be certified according to the GB 4806.7-2016 standard to ensure that harmful substances such as plasticizers and volatile organic compounds will not be released when brewed in 100 ℃ hot water. Compared to ordinary coated paper, its coating thickness is more uniform (usually controlled at 15-20 μ m), which can avoid the risk of water leakage caused by local thinness, and will not affect the bending adaptability of the paper due to excessive thickness. This echoes the precise dimensions of "barrel net diameter 114 ± 1mm" and "lid diameter 117 ± 1mm", making the lid tightly and less likely to be damaged.

The adaptability of material characteristics to usage scenarios can better enhance user experience. The oil resistance of PE coating allows it to directly come into contact with fried dough and seasoning oil bags, avoiding packaging softening caused by oil penetration; The stiffness of the paper itself is matched with the barrel design of "height without lid 110 ± 1mm" - it will not collapse due to excessive softness, and can maintain stability during stacking (the conical structure with a lower diameter of 93 ± 1mm further enhances stacking stability). In addition, the heat sealing property of PE coating allows the seams of the barrel to be tightly sealed through high-temperature pressing. With the dimensional accuracy of the lid, it can effectively isolate external moisture and extend the shelf life of food, which is crucial for barrel packaged fast food that requires long-term storage.

For production and branding, this material also has significant advantages in process adaptation. PE coated paper has strong printing adaptability, can carry high-definition patterns and text information (such as brand logos and certification marks), and the ink is not easily smudged due to moisture; Its cutting and forming accuracy is high, and it can match size requirements such as "with a covered diameter of 117 ± 1mm", reducing the rate of defective products in the production process. When consumers see the clear "food grade PE coating" label on the packaging, combined with the usage experience of "no water leakage or softening during brewing", they will naturally associate the stability of the material with the reliable image of the brand.

More importantly, this material strikes a balance between environmental friendliness and practicality. PE film that meets the standards can be separated and recycled from paper, and some brands also use biodegradable PE raw materials to respond to the trend of "green packaging". This composite advantage of "stability+practicality+no guarantee" makes food grade PE coated paper go beyond its simple "packaging material" attribute and become a carrier for brands to convey concepts such as "attention to detail" to consumers. The size design transforms this concept into a perceptible user experience.
