What is hot melt adhesive for Foam Packaging?

EPE Foam is a new type of environmentally friendly packaging material. It can effectively absorb impact forces and plays a good protective role for fragile and vulnerable items. Hot melt adhesive manufacturers provide eva hot melt adhesive or polyolefin hot melt adhesive for foam to foam and eva foam sealing.


Advantages:

Fast Curing Speed: Improves bonding efficiency and adapts to mass production. After application, the hot melt adhesive achieves initial fixation in seconds, avoiding assembly displacement or debonding caused by slow curing.


High Bonding Strength: Stable connection without detachment, impact resistance, and aging resistance. After curing, the hot melt adhesive forms a high-strength bond with the mattress fabric; during peeling, the filter medium (mattress fabric) breaks while the adhesive layer remains intact.


Good Thread-Breaking Performance: Optimizes operational experience and avoids contamination. When pausing or switching substrates during bonding, the hot melt adhesive rarely leaves residual stringing. No excess adhesive threads wrap around equipment or adhere to product surfaces, preventing product contamination or appearance damage.


Good High-Temperature Resistance: Adapts to extreme storage environments for long-term stability. It can withstand high temperatures, and the adhesive layer will not soften or flow when exposed to prolonged high-temperature conditions. When products are stored in high-temperature warehouses or transported outdoors in summer, the bonded areas remain firmly attached, preventing debonding due to high-temperature aging—especially suitable for customers in high-temperature regions.


Low Odor: Compliant with environmental standards and suitable for clean scenarios. The hot melt adhesive features a low-VOC formula, releasing almost no odor during curing. It does not irritate operators in the assembly workshop or contaminate mattress fabric; finished mattresses have no residual adhesive odor. No odor is generated from adhesive layer decomposition during long-term use.

How to use?

•Manual Glue spreading Machine: Multiple operators can work on one machine; Low equipment investment cost; Wide applicability.
Manual Glue - spreading Machine
•Automatic Coating and Gluing Machine: High efficiency and fast speed; The gluing machine is far from the operator, with less odor; No contact with the glue tank, reducing the risk of burns.

Usage and Precautions

•Open Time: 30 - 40 seconds

•Operating  TemperatureSettings: Glue melting tank: 160 - 200°C; Coating roller: 150  -180°C. Note: In cold environments, the hot - melt adhesive dissipates heat quickly, and  theoperating  temperatureof the hot - melt adhesive needs to be increased by at least 10°C.

In addition, the following precautions should be taken:
1.Pre - heat the glue - melting device for about 2 hours first.

2.Control the amount of glue added according to the production volume to  preventover  -heating due to incomplete consumption over a long period, which may cause the glue to  ageand affect its adhesion. Also, avoid insufficient consumables, which may affect glue spraying.

3.The bonding work must be completed within the open time of the glue. Clamp  theadherends until they are completely cooled and cured.

4.Since the glue - melting tank and the glue - spraying system are at high temperatures, safety
protective equipment must be worn during operation to prevent burns.

5.The use place should be well - ventilated and kept away from open flames.
6.Avoid contact between the melted glue and parts such as eyes and skin.

7.If the melted glue comes into contact with the skin, immediately immerse the affected skin  incold water and rinse for at least 10 minutes. Seek medical treatment in a timely manner after cooling.

Why choose UNIS?

•Good Transparency: The overall visual effect of EPE Foam packaging will not be affected by the opacity of the hot - melt adhesive.

•Low Odor: Reduces the impact of pungent odors on the health of operators and prevents the transfer of the packaging material's odor to the product.


•Good Fluidity: It can be quickly and evenly coated on the surface of the adherend and fit well, ensuring the integrity of the bond.

•Fast Curing Speed: Enables the adherends to be fixed quickly, greatly shortening the production cycle.

•High Bonding Strength: It has good bonding performance with a variety of materials, ensuring that the bonded objects will not easily fall off or separate.

•Good High - Temperature Resistance: It can still maintain good bonding strength and stability in a certain high - temperature environment, making it suitable for high - temperature applications.


•Environmentally Friendly and Harmless: It is made from environmentally friendly raw materials, causing no pollution to human health and the environment. It can be widely used in fields with high environmental requirements.
