Direct answer: When printing and packaging companies conduct environmental impact assessments or apply for pollutant discharge permits, it involveshot melt adhesiveThere are usually five types of particle information – product MSDS (Safety Data Sheet), component and solid content description, VOCs and non methane total hydrocarbons generation basis, annual dosage and process addition method description, supplier qualification and third-party testing report. If these five materials are complete, the environmental impact assessment unit can basically calculate the rubber particles clearly.

In the past, when conducting environmental impact assessments, the focus was on solvent based materials such as ink, car wash water, and laminating adhesive. Hot melt adhesive particles were often overlooked because they did not contain solvents. In the past two years, the issuance of pollutant discharge permits in various regions has become increasingly detailed, and the heating and volatilization of the melt adhesive process has been separately accounted for. Many printing factories only discovered during the correction stage that they only have a delivery note issued by a supplier, which cannot be connected into separate tables.
| Document Name | Purpose | Key field |
|---|---|---|
| MSDS Safety Technical Data Sheet | Hazard assessment, storage and transportation requirements | Composition, flash point, softening point, hazard classification |
| Composition and Solid Content Description | Calculate the organic content | Basic resin, tackifying resin, wax, solid content of 100% |
| VOCs based on materials | Calculate the total non methane hydrocarbon production | Heating temperature range and volatile matter test data |
| Annual usage and process description | Material balance calculation | Year/year, feeding method, melt adhesive temperature |
| Qualification and Testing Report | Compliance of supporting materials | Business license RoHS、 Heavy metal detection |
When supplying Sunlife hot melt adhesive, Guangzhou Sunlife Trading will organize it into a data package according to the model provided by the customer, including MSDS, component description, testing report, and recommended temperature range for the adhesive, which is convenient for printing factories and environmental assessment units to directly reference. The model information commonly used by customers for book binding, packaging and packaging, and quick printing of graphics and text is readily available and usually does not require additional waiting.
Conventional EVA and APAO hot melt adhesive particles are solid and solvent-free, and are generally not listed in the hazardous chemical catalog. However, MSDS is still required as a basis for storage, transportation, and occupational health.
In some regions, it is allowed to substitute manufacturer self inspection data with a commitment letter. However, when it comes to export or food contact packaging, it is recommended to conduct third-party testing to avoid being required to rectify in the future.
need. The material list in the environmental impact assessment and pollutant discharge permit corresponds to the specific supplier and model. After replacement, the MSDS and testing report should be updated in a timely manner to maintain consistency in the ledger.
Direct answer: The most secure arrangement for sealing and gluing points is to leave 20-30mm at both ends, evenly distribute in the middle, and cover a total length of about 60% -70% of the sealing length. The common three-point, five point, and strip continuous methods have their own applicable scenarios. Choosing the wrong arrangement not […]
What should I do if the hot melt adhesive particles are not firmly attached to the coated paper? Direct answer: The root cause of the poor adhesion of laminated paper is mostly due toLow membrane surface energy, glue not eating paper fibers, poor coordination between opening time and compressionThese three points. The surface of laminated […]
When maintaining high-performance operation of the hot melt adhesive machine, you can take many measures to reduce downtime and improve system performance. Please remember that downtime equals production loss. 1) Apply hot melt adhesive at the correct temperature. Using the correct settings can avoid many troubles. You may also want to try using a metallocene […]
The common quality problems of wireless binding hot melt adhesive mainly include page dropping, uneven back, broken book core, bubbles, and perforation at both ends of the book. They often appear on single or multiple banks, mainly due to the following reasons: 1、 Analysis of Page Dropping Reasons (1) The milling groove is too shallow […]
