🌿 PFAS-Free🛡️ Oil-proof and impermeable🍔 fast food packaging♻️ Recyclable category📄 Lightweight design🌍 Export-friendly


Paper-based and circular-friendly

Focus on recyclable and repulpable solutions, helping brands to advance ESG goals.

Lightweight Cost Reduction

Supports lightweight weight ranges such as 23g–40g, suitable for mass catering supplies and fast food chain applications.

Excellent Oil Resistance Performance

For oily foods such as hamburgers, fried chicken, french fries, baked goods and tray liner paper reduce oil stains, oil penetration and paper darkening.

Fluorine-free oil-resistant system

Avoid controversies surrounding traditional PFAS / PFOA oil repellents through material design, aligning with the trend toward stricter standards for food-contact packaging.

Traditional Packaging Pain Points

Why do food greaseproof papers need to be upgraded

Traditional oil-proof packaging for conventional food mainly relies on PE coated paper, silicone oil paper or fluorine-containing oil repellents. Though these solutions were once mature, they are facing mounting pressure in terms of food safety, environmental recycling and international compliance.

Compliance pressure for PFAS-Free oil resistance

Fluorinated substances such as PFAS and PFOA have drawn continuous regulatory attention in European and American markets, and export clients as well as international catering brands are increasingly shifting toward fluorine-free solutions.

Difficult to separate paper from film layer

It is difficult to separate the paper from the film layer, which results in high recycling costs and great difficulties in repulping, and hinders the circular utilization of paper-based packaging as well as brands' plastic reduction goals.

Difficult to recycle PE coated paper

It is difficult to separate the PE film layer from paper fibers, which results in high recycling costs and great difficulties in repulping, and hinders the circular utilization of paper-based packaging as well as brands' plastic reduction goals.

Core Technologies & Advantages

Core Advantages of GP Series

The value of the GP Series lies far beyond just oil resistance; it strikes a balance among oil-repellent performance, food contact safety, lightweight cost efficiency, eco-friendly recyclability and global regulatory compliance.

Direction of recyclable re-pulping

Retain the recyclable properties of paper-based packaging and help customers replace traditional coated paper and laminated paper.

Lightweight Material Design

It can produce lightweight oil-proof packaging, suitable for fast food, takeout and disposable catering supplies.

High oil resistance, not easy to seep

For oily food contact applications, reduce grease penetration, oil stains and surface contamination.

PFAS-Free Safety Direction

It does not rely on traditional fluorinated oil repellents, better aligning with the global trend of fluorine-free food packaging.

Series Boundary

How to distinguish the GP series from other series?

Within Ruize's product portfolio, the primary core capability of GP is oil resistance. It has clearly defined boundaries with series including WGS, HOPS, HMPS and HBPS.

HBPS

Resolve "Oxygen + Water Vapor"

High oxygen barrier, high moisture barrier and heat-sealable, suitable for flexible packaging of high-value foods with long shelf life such as coffee, tea, nuts and freeze-dried products.

WGS

Resolve "water + oil + heat sealing"

Three-in-one waterproof, oil-proof and heat-sealable material, mainly applied to water-based coated paper cups, paper bowls, food containers and heat-sealing strips for popsicle paper wrappers.

GP

Mainly target oil-related issues

Oil-proof and resistant to grease penetration, suitable for food service papers that do not necessarily require heat sealing, such as hamburger paper, fried chicken paper, tray liner paper and baking liner paper.
