Biodegradable plastic-free food-grade molded pulp

WHAT IS BIODEGRADABLE FLUORINE-FREE FOOD-GRADE COATING?

（Water repellent agent/Oil repellent agent)

(In order to increase the water and oil resistance of pulp molding, the current production process is to add a large number of water and oil repellent agents to the pulp.)

Biodegradable 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 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, water repellent agents and oil repallent agents. It can reduce the difficulty and cost of product recycling.

We just need to apply the fluoride-free food grade coating to the surface by spraying it.

(SVHC TEST REPORT)

Plastic,water repellent agents and oil reprllent agents can improve the physical properties of the product such as barrier and heat sealing, but the they are difficult to recycle and degrade, increasing the cost of recycling. And it's not friendly to the environment.

(Paper with PE material)

If we combine the mulded pulp with Biodegradable fluorine-free food-grade coating, we can better solve the physical properties and recycling problems of the paper after plastic, oil repellent agents and water repellent agents removal.

For example,the common food grade paper packaging material ingredients is Paper+PE/PP/Other plastic and Paper+aluminum foil+PE/PP/Other plastic. Nowaday, Fluorine-free food-grade coating can replace PE/PP/Other plastic, and it can bring excellent physical properties. Because Fluorine-free food-grade coating is biodegradable, it can reduce the difficulty of recycling and reduce the 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.

Similarly, we can apply our Biodegradable fluorine-free food-grade coating to pulp molding.

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 fluorine-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
