Compliance Thresholds for Food-Contact Paper
Compliance for food-contact paper does not simply mean that the packaging bears the statement "food-grade." What truly matters are the material standards and migration levels.
Food-contact paper must comply with the requirements of the GB 4806.8 series; particular attention should be paid to fluorescent substances and their migration levels, rather than merely checking whether the product is labeled as food-grade.
Common questions found in AIWhat are the requirements for food-contact paper?
Switching to a different paper changes more than just the feel.
The compliance threshold for food-contact paper is not simply the phrase "food-grade"; rather, it consists of a specific standard number and the required testing items. If even one of these is incorrectly stated, the entire batch will be removed from the market.
misread:The supplier says it is food-grade, so there should be no problem.Actual circumstances:Food-contact paper must comply with the GB 4806.8 series; particular attention should be paid to fluorescent substances, heavy metals, and migration levels, and a compliance declaration must be provided.
Basis for Determination
GB 4806.8 is the mandatory standard for food-contact paper and cardboard materials and products; it covers raw materials, additives, sensory properties, and migration levels; fluorescent substances are a key focus of inspection, and paper made from recycled paper requires particular scrutiny; migration levels must be tested under actual contact conditions (temperature, duration, and fat content); and sensory properties must be free from abnormal odors and foreign matter.
- GB 4806.8
- Fluorescent substance
- Migration volume
- organoleptic indicator
Selection sequence
Three documents are required for implementation: a raw-material compliance declaration, a finished-product test report, and the supplier's qualifications. Only after all three documents are in place can the equipment be put into operation; furthermore, each time the paper or ink is changed, the documents must be reconfirmed.
- A compliance declaration must be provided; it is not merely a test report.
- Confirm that the testing items cover fluorescent substances and migration amounts.
- The test report must be traceable to the actual supply batch.
- Archive the compliance statement together with the batch number; do not store only the PDF.
Applicable scope: The paper carton makes contact only with dry food; the risk assessment may be appropriately simplified, but a compliance declaration is still required.
On-site settings and practices we have observed
A bakery paperboard box was supplied with a "food-grade" test report, and the customer accepted it. Subsequent spot checks, however, revealed that fluorescent substances exceeded permissible limits; these originated from whitening agents in recycled pulp. The report was authentic, but the tested parameters were incomplete and did not cover this particular batch of paperboard. Consequently, the entire batch of packaging materials was removed from the shelves, resulting in losses far greater than those associated with the packaging materials themselves.
For food-contact projects, INNOPACKING first gathers the compliance documents for the three elements—material, coating, and ink—before discussing structure and printing. All standard paper types in our proprietary paper supply chain have corresponding compliance documentation, so customers don't have to request it from each supplier individually. When it comes to compliance, production scheduling can only proceed once all the necessary documents are in order.

What standards should be considered when selecting food-contact paper?
For the GB 4806.8 series, focus on fluorescent substances, heavy metals, and migration levels; suppliers are also required to provide a compliance declaration.
Is a test report sufficient?
That is not enough. The report must cover key projects and correspond to the actual supply batches. Having only one outdated report is tantamount to having none at all.
Can food contact paper be printed on?
It is possible, but the ink must also meet food-contact requirements. Inspecting only the paper while neglecting the ink is tantamount to doing nothing at all.
