Choosing a hot melt adhesive manufacturer is not about making someone’s slogan sound louder, but about choosing oneCan match your substrate and equipment, deliver stably, and have access to relevant informationThe supplier. The following 5 items are recommended to be aligned one by one in order, which is much more reliable than just looking at one quotation. This article is compiled by Guangzhou Sunlife for reference by procurement and process personnel.
Many buyers ask at the beginning, ‘What is your annual production capacity?’. But the production capacity istotal amountThat doesn’t mean the model you want is in stock.
What should be asked more is:
Hot melt adhesive can be divided into edge adhesive and back adhesive according to its purpose, with shapes including cylindrical particles, round particles, and block shapes; The models required for different scenarios are not universal.First confirm if there is the one you want, then discuss the quantity.(This article does not make any promises about specific production capacity figures, and the relevant statements should be based on the actual information of the company.)

A reliable manufacturer, the testing data isDistinguish the model and match the batchIt’s not a universal report that will conquer the world.
Sunlife hot melt adhesive has SGS RoHS testing data for 2026 (report number CANEC260086412012026-04-15, with no detection of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, and four adjacent benzene compounds).

Additionally, the Environmental Labeling Certification Certificate is valid until August 1, 2026 and has now expired,Not cited as a valid current qualification。
The interruption of rubber material supply often directly leads to line shutdown. So the third item to consider is:
These are not just words, it depends on the manufacturerWarehouse, shipment, and arrival acceptance photosThe most direct.
This is the most easily overlooked point. Based on Sunlife’s after-sales experience,About 90% of after-sales service actually stems from equipment temperature control failure——The temperature control meter shows 160 ℃, but the actual temperature of the glue tank may only be 100 ℃. Changing the glue won’t solve this problem, we need to calibrate the equipment first.
A good supplier will accompany you to investigate: glue temperature, glue amount, opening time, equipment speed, workshop environment temperature, rather than just saying “try changing to a more expensive glue”.
Finally, it’s time for price comparison. Similarly, it is important to clarify:
It’s much easier to clarify these before cooperation than to argue afterwards.
Q: There are so many hot melt adhesive manufacturers in Guangzhou, what should we first look at?
A: First, let’s see if you can supply the model I use for this production line. The model doesn’t match, the rest is just empty talk.
Q: How to determine if a supplier’s adhesive can be used on my equipment?
A: Explain your substrate (paper weight/coated or not), equipment type, operating speed, glue tank temperature, and process clearly, and ask the other party to provide selection and verification suggestions based on these conditions. Then, start with a small sample installation.
Q: How should I read the test report?
A: Check three points – whether the testing items cover the ten RoHS requirements, whether they match your model, and whether the report is within the validity period. General reports should be handled with caution, and it is best to request accompanying reports for the corresponding batch.
Q: Can you send samples for sampling?
A: Okay. After providing the conditions for use, in most cases, sampling and trial assembly of small samples can be arranged before deciding on the batch size.
