What documents are required for the environmental impact assessment of hot melt adhesive particles? One time preparation list for printing and packaging factory

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.

Industry background: Rubber particles have become a mandatory item to be checked from “auxiliary materials”

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.

User pain point: If the information cannot be filled in, the project will have to wait

• Only the product name, without the model and base resin type, the environmental assessment unit cannot apply the emission factor.
• The MSDS is an old version from a few years ago, and the signing unit does not match the actual supplier, so it has been requested to be reissued.
• The annual usage is calculated backwards based on the purchase amount, resulting in significant errors and higher emissions, which in turn increases the investment in governance.
• Traders cannot obtain the original factory inspection report and can only resubmit for inspection, causing delays of half a month.

Comparison Table of Five Types of Data

Three practical suggestions for preparation

• First determine the model and then report the quantityThe softening point difference of the same brand but different models is 20 ℃, and the melt adhesive temperature is different, resulting in different accounting results.
• Usage is calculated according to the ledgerPulling the actual consumption of the past 12 months from the material requisition ledger is much more accurate than converting it based on the purchase amount.
• Request the complete set at onceWhen requesting information from suppliers, bring up all five categories together to avoid repeated communication.

The blending method of Sunlife hot melt adhesive

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.

Frequently Asked Questions

Are hot melt adhesive particles classified as hazardous chemicals?

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.

Can I pass without a third-party testing report?

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.

Do I need to provide new information when changing suppliers?

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.
