Food-Safe Biodegradable Paper

Food Safe Biodegradable Paper is an environmentally friendly packaging material designed specifically for food contact scenarios, using natural plant fibers (such as wood pulp, bamboo pulp, or agricultural waste) as the substrate, combined with bio based coatings or processes without chemical additives. Its core advantage lies in its compliance with food safety standards (such as FDA, GB 4806, etc.), as well as its biodegradability, compostability, or recyclability. It is widely used in food packaging, catering services, and retail fields, and is a green alternative to traditional plastics and non biodegradable paper.

characteristic

Natural plant fiber substrate

Raw material source: Mainly renewable resources (such as FSC certified fast-growing forest pulp, bamboo pulp, or sugarcane bagasse) to reduce the consumption of forest resources.

Data support: Renewable fibers account for over 95% of the substrate, and the carbon emissions during the production process are reduced by 60% -80% compared to traditional plastic packaging. For example, the carbon emissions from producing 1 ton of food grade biodegradable paper are approximately 0.8 tons of CO ₂ equivalent, while traditional plastic packaging is 3.2 tons.

Non toxic coatings and additives

Safety standards: The coating uses water-based acrylic acid, chitosan, starch based polymers and other bio based materials, without adding fluorinated compounds (such as PFOA, PFOS), phthalates or heavy metals.

Data support: Certified by FDA 21 CFR 176.170 (Food Contact Paper) and GB 4806.8-2022 (Food Contact Paper and Paperboard Materials and Products), with a total migration of ≤ 10 mg/dm ² (40 ℃, 10% ethanol solution, 2-hour testing conditions), and no heavy metals (lead, cadmium, mercury, etc.) detected (detection limit of 0.01 mg/kg).

Efficient oil and moisture resistance performance

Function implementation: Through micro scale biological coating technology, a dense barrier layer is formed on the surface of the paper, effectively blocking the penetration of oil, moisture, and seasonings.

Data support: The oil resistance level reaches Kit 10-12 (TAPPI T 559 standard), which means it can withstand continuous oil contact for 10-12 hours without penetration; The moisture resistance performance is manifested by a water vapor transmission rate (WVTR) of ≤ 15 g/(m ² · 24h) under 38 ℃ and 90% RH conditions, which is superior to ordinary paper (WVTR 30-50 g/(m ² · 24h)). For example, if the package contains explosives with an oil content of 25%, the surface oil penetration rate will be less than 3% within 4 hours.

Degradability and compostability

Degradation cycle: Under industrial composting conditions, it can be completely degraded into carbon dioxide, water, and biomass within 180 days, in compliance with EN 13432 and ASTM D6400 standards.

Data support: Laboratory simulation composting tests show that the degradation rate reaches over 85% within 90 days, and the final residue is only inorganic salts and trace organic matter. Compared to traditional plastic packaging (which takes over 450 years to degrade), food grade biodegradable paper reduces its environmental load by 99%.

High temperature resistance and thermal stability

Performance: The coating can withstand high temperatures of 180-230 ℃ and is suitable for oven heating, microwave reheating, and steam cooking.

Data support: Heating continuously at 220 ℃ for 20 minutes without deformation, coking, or coating peeling of the paper; After microwave heating (800W, 3 minutes), the surface temperature of the paper is ≤ 80 ℃, and no harmful substances are released. The tear resistance strength reaches 1.8-2.8 kN/m (GB/T 455-2002 standard), which can withstand heavy food packaging requirements.

Printing and customization capabilities

Process support: Compatible with water-based ink, soy ink, and UV curable ink, with a pattern clarity of ≥ 600 DPI and a color reproduction degree Δ E ≤ 3 (CIE 1976 standard).

Data support: The printing adhesion reaches 5B (ASTM D3359 standard), and the ink detachment rate is less than 3% after 500 back and forth friction tests, meeting the visual and durability requirements of brand packaging.

Application scenarios

Fast food and delivery industry

Requirement: Replace plastic burger boxes, french fry bags, and takeaway food box liners to reduce plastic pollution.

Case: An international fast food brand upgraded its hamburger packaging paper to food grade biodegradable paper, resulting in a reduction of 1.5 tons of plastic usage per store per month and an increase in packaging waste recycling rate from 12% to 80%. Consumer research shows that 75% of customers have increased their willingness to repurchase due to eco-friendly packaging.

Baking and Pastry Industry

Requirement: Packaging paper cupcakes, bread, cookies, and other foods with high oil or sugar content must be oil proof, moisture resistant, and heat-resistant.

Case: A chain bakery used biodegradable paper to wrap croissants. After reheating in a 200 ℃ oven for 5 minutes, the paper did not char, the oil penetration rate decreased to 1.8%, and the product shelf life was extended by 2 days.

Frozen Food and Cold Chain Logistics

Demand: It is used for frozen pizza, Spring rolls and other prepackaged food, and its physical properties should be stable at -18 ℃.

Case: A frozen food company used biodegradable paper to wrap frozen dumplings. After being frozen at -18 ℃ for 9 months, the paper did not become brittle or crack, and the oil resistance performance still met Kit 10 standards after thawing.

Coffee and tea beverage industry

Requirement: To produce coasters, oil resistant liners, or biodegradable cup lid liners to enhance the brand's environmental image.

Case: A well-known coffee brand has launched biodegradable paper cup pads, which can be used in conjunction with compostable paper cups to reduce the carbon footprint of single cup packaging by 40%, attract environmentally friendly consumer groups, and increase brand premium by 15%.
