Yiwu Zhouyi New Materials Co., Ltd. presents adhesive quality inspection and formulation inspection in its existing company materials. Buyers should agree the exact product specification and acceptance criteria for each wholesale or OEM project.
Start with an Agreed Specification
Identify the adhesive grade, net weight, container, retail pack and artwork version. Request technical and safety information for the selected product. These references give your team a clear basis for sample evaluation and repeat orders.
Questions to Review Before Production
- Which product and packaging checks apply to this order?
- What materials and test conditions will be used for sample evaluation?
- How will fill quantity, container closure and label details be assessed?
- Which batch identifiers and supporting documents are available?
- What acceptance criteria and packing configuration have both parties agreed?
This is a buyer review checklist. Specific test methods, inspection records and documentation availability must be confirmed with our team for the selected product.
Evaluate the Sample on Your Actual Materials
Record the surfaces, preparation, application method and time before assessment. Distinguish fixture time from full cure, and compare results under agreed conditions. Package size alone does not prove compatibility, curing speed or strength.
Keep Repeat Orders Clear
Keep the approved sample, written specification and artwork reference together. Identify any requested change to adhesive grade, packaging or labeling before placing the next order.
