Customer Frequently Asked Questions FAQ

This is a bio-based water-based barrier coating for paper-based food packaging. Its function is not to turn paper into plastic, but to form a continuous barrier layer on the surface of paper fibers to improve water resistance, oil resistance, moisture resistance and subsequent processing stability. The specific performance needs to be verified based on the base paper, coating and molding conditions.

Usually used for base paper for paper cups and bowls, molded pulp, paperboard, white paperboard, kraft paperboard, burger wrap paper, greaseproof paper and other substrates. Whether it can be reliably introduced into production needs to be evaluated based on the basis weight of the base paper, surface sizing, smoothness, absorbency, equipment conditions and subsequent molding methods.

The core of the coating is a bio-based PHA combined with a water-based dispersion system that forms a barrier layer through film formation. The actual solution will be adapted based on barrier objectives, drying conditions and machine window, and should ultimately be subject to TDS, sample testing and project verification.

Whether it is biodegradable needs to be confirmed based on the specific product version, certification scope, final product structure and target market requirements. If customers require statements related to industrial composting or home composting, they should make judgments based on corresponding standards, test results and certification documents.

Bioten™ coatings help paper-based materials improve their barrier properties against liquids, grease and water vapor compared to regular paper, while maintaining the ability to assess paper-based processing and recycling pathways. It still belongs to the paper-based material system and needs to be verified according to specific application conditions.

It is recommended to understand it as "development for food contact packaging scenarios". Whether it meets the requirements of the target market needs to be comprehensively confirmed by combining food contact regulations, migration testing, DoC documents and final product structure.

Coating thickness is usually more suitable to be communicated by coating amount and film formation state. The specific dosage will be affected by the base paper, barrier target, equipment conditions and subsequent molding methods. It is recommended to refer to project sample trials, TDS and third-party test results.

Under proper drying and coating conditions, paper feel and stiffness can be maintained within acceptable limits. Specific changes depend on coating dosage, base paper fiber structure, drying conditions and finished product structure.

Print suitability can be assessed on a project-by-project basis. In actual applications, it is recommended to make printing proofs first, and then confirm the color performance, adhesion, ink system and subsequent processing adaptation.

Rain-proof or water-repellent applications focus on the impact of external liquid water and condensation on the paper-based structure and are not the same as a completely sealed container. When used in takeout paper bags, cold-chain handling and outdoor short-term contact scenarios, it is recommended to verify according to actual working conditions.

The coated surface can provide water resistance under suitable film-forming conditions, but the paper base will still be affected by long-term immersion. It is necessary to distinguish between "coating water resistance" and "paper base immersion resistance" and confirm with specific application tests.

Moisture barrier performance refers to reducing the water vapor transmission rate and helping to slow down the entry of environmental moisture into the packaging. It is important for biscuit, potato chip, bakery and tea packaging, and its specific performance needs to be confirmed by combining WVTR testing, packaging structure and shelf life design.

Paper cups are one of the typical applications of Bioten™. When introducing it into production, it is necessary to confirm whether the cup body, cup bottom, folding edge and heat sealing structure match, and carry out machine trials according to the specific cup type, equipment conditions and product requirements.

The paper-based solution can be used as an evaluation direction for some applications, provided that the aroma retention, storage and transportation conditions and target market requirements are clear.

Nut packaging usually pays attention to oil oxidation, moisture and oil resistance at the same time. It is recommended to carry out verification around moisture resistance, oxygen barrier, oil resistance and shelf life of the whole package.

Application evaluation can be carried out in high-humidity environments, but the focus needs to be on blocking between layers of wound material, rewinding stability, storage stacking and packaging structure. It is recommended that environmental controls be verified along with material performance.

Oxygen barrier and moisture barrier performance are closely related to coating integrity, storage environment and usage conditions. Barrier performance should be re-evaluated if packaging experiences cracks, punctures or extreme heat and humidity.
