Non Plastic Coated/PLA Coated Paper Roll Paper Cup Raw Material

The oil and water resistance of plastic-free coatings on paper cup paper compared to PE coatings has distinct characteristics:

Water Resistance

● Plastic-free coatings: Special molecular structures and processing create a tight waterproof barrier, effectively preventing water penetration for daily use. However, their performance may slightly lag behind PE in prolonged contact with large amounts of water or high humidity, where PE better maintains cup integrity and strength.

● PE coatings: Excel in water resistance, providing long-term moisture barrier. They resist water-induced deformation or damage even in wet environments or after prolonged water contact.

Oil Resistance

● Plastic-free coatings: Some types, with special anti-oil agents or surface treatments, offer moderate oil barrier for general food packaging (e.g., low-fat beverages). But for high-oil liquids or long-term exposure, their resistance is typically inferior to PE.

● PE coatings: Show strong oil tolerance and barrier properties, effectively preventing all types of oil penetration. This ensures stability and hygiene when holding greasy foods or drinks, without oil-induced appearance or performance degradation.

Overall, while plastic-free coatings may trail PE in certain oil/water resistance scenarios, ongoing technological improvements are closing the gap. They already meet most common cup usage needs while offering environmental advantages.

Under the demands of the market and the overall environment, plastic-free coating lamination(non-plastic coating) has gradually replaced PE lamination as an environmentally friendly and degradable material.

● Catering industry: Disposable paper cups (for cold and hot drinks), noodle bowls, soup buckets.

● Takeout packaging: oil-splashed noodle boxes, fried chicken boxes, French fries cups, salad bowls.

● Food retail: baking packaging, fresh food trays, outer packaging for frozen foods.
