Technical repulpability, local recyclability, industrial composting, household composting and natural environmental degradation are different disposal paths, and corresponding information should be prepared separately.
Enter recycling and disposalFrequently asked questions: High-frequency judgment in project communication.
Are water-based coatings equivalent to plastic-free materials?
They cannot be simply equated. Water-based describes the processing system or dispersion medium. Whether it is a plastic needs to be comprehensively judged based on polymer properties, regulatory definitions, certification standards and target market requirements.
Does biobased equal degradable or compostable?
Cannot be directly equated. Biobased describes the source of raw materials, and degradable or compostable describes end-of-life disposal performance. Both types of claims usually require comprehensive judgment based on test methods and disposal conditions.
Does repulpable reporting equate to local recycling?
Cannot be directly equated. Respulpability is a technical test result, and local recyclability also depends on the collection system, sorting capabilities, paper mill acceptance conditions and pollution control.
Can food contact testing cover all compliance requirements?
It usually requires further confirmation based on the product structure and usage conditions. Food contact testing is used for safety and migration evaluation, but also requires attention to barrier properties, heat sealing mass production, recycling disposal, source traceability and statement expression.
Can the same report cover multiple products?
Need to be evaluated based on product differences. Report coverage should be reviewed when there are changes to the base paper, coating, coating volume, printing, adhesive, molding process, and usage conditions.
How can green statements be expressed more securely?
It is recommended to use verifiable and conditional statements, such as clarifying test conditions, applicable uses, target markets and disposal conditions, to avoid absolutes, generalizations or cross-market application.
