Biodegradable Fluorine-free food-grade baking paper

WHAT IS BIODEGRADABLE FLUORINE-FREE FOOD-GRADE COATING?

Fluorine free food grade coating has passed the SVHC test by SGS and the biodegradable testing by SGS. 

Its advantages are heat sealable, gas barrier, liquid barrier, wear resistance, high and low temperature resistance and biodegradable. And its use method is simple, does not need to change the original production equipment and facilities, can be used on the original equipment.

The application of biodegradable fluorine-free food-grade coatings on packaging can reduce or replace the use of plastic materials, and can reduce the difficulty and cost of product recycling.

(SVHC TEST REPORT)

Coating the paper with silicone oil or adding fluoride can provide the barrier property and high temperature resistance of the paper, but it will release substances harmful to the human body at high temperatures. Some paper will be combined with plastic, which will increase the barrier property of the paper, but at the same time make the paper difficult to recycle and degrade.

If we combine the paper with biodegradable fluorine free food grade coating, we can better solve the physical properties and recycling problems of the paper.Our coatings are high and low temperature resistant, able to withstand temperatures as low as minus 30 degrees and as high as 180 degrees.The material itself does not contain fluorine, so no fluoride is produced during heating.

At the same time, our materials do not contain any plastic components, and can be biodegradable, which can reduce the difficulty and cost of recycling during the product recycling process.

HOW ABOUT PHYSICAL PROPERTIES OF BIODEGRADABLE FLUORINE-FREE FOOD-GRADE COATING

Biodegradable fluorine-free food-grade coating can better replace the heat sealing of plastic, so that the paper is well bonded together under heating, and the product can reduce the use of plastic or no plastic.

In order to know its heat sealing strength, we have done a set of tests, and we can invite customers to apply for samples to test themselves.

After heat sealing, we hang 5KG of sand on the biodegradable fluorine-free food-grade coating paper bag for a week, coating can keep the hot sealing place from breaking or cracking.

Without any plastic material.

Biodegradable fluorine-free food-grade coating combine with paper or aluminum foil paper has excellent gas barrier performance.

We completed the test of two schemes, respectively, the composite of paper and coating, and the composite of aluminum paper and coating.

The WVTR and O2TR are shown in the figure above.

We can also improve the material scheme according to the customer's data requirements.

Oil proof(silicone oil) paper(current market product) can achieve 6-8 grade.

Normal and high temperature oil on the oil proof paper within a fixed time,the paper has a large amount of oil stains.

（The result is shown in the figure below)

Biodegradable fluorine-free food-grade paper can achieve 12 grade.

Normal and high temperature oil on the biodegradable fluorine-free food-grade paper within a fixed time has no stains.

（The result is shown in the figure below)

Biodegradable fluoride-free food-grade coating has high and low temperature resistance, from 180 degrees to minus -30 degrees will not change the performance of the product, and can be used without changing the production equipment of the customer.

BIODEGRADABLE FLUORINE-FREE FOOD-GRADE COATING CAN REDUCE THE RECYCLING COST OF THE PRODUCT

Under the experimental condition,the average biodegradable rate of 10-d window was 52.42%.The average biodegradable rate of the tested sample was 84.68% after 28 days.

The biodegradable fluorine-free food-grade coated packaging can be recycled into pulp, which can reduce the impurities of pulp, improve the recovery rate of pulp, and reduce the recycling cost of enterprises.

BIODEGRADABLE FLUORINE-FREE FOOD-GRADE COATING CAN BE USED ON THE ORIGINAL PRODUCTION EQUIPMENT

1. Single component 

2. Can be coated on offset/gravure 

printing lines 

3. No need to change the original process route 

4. No need to modify equipment
