The production of Double Sided Foam Tape adhesive is a precision coating technology engineering, its core is to combine the adhesive evenly and stably on the foam substrate. The whole process can be divided into the following key steps:
Stage 1: Substrate Preparation and Pretreatment
1. Unroll and test the foam base material
The large roll of foam base material (such as polyethylene PE, polyurethane PU, or acrylic foam) is installed on the unwinding frame.
The process is equipped with an online defect detection system, which automatically identifies and marks impurities, holes or uneven thickness defects on the surface of the substrate through cameras or sensors to ensure the quality at the source.
2. Corona treatment
The foam base material is processed through a corona treatment machine. High-frequency high-voltage discharge alters the molecular structure of the foam surface, increasing surface energy and roughness.
Purpose: To greatly improve the wettability and bonding strength between the surface of the foam and the adhesive, and prevent the separation of the adhesive layer and the substrate in the subsequent use.
Stage 2: Precision Coating and Compounding
3. Adhesive preparation and coating
The solid acrylic adhesive raw material is dissolved in organic solvent to form a glue with a certain solid content and viscosity. Or use the solvent-free liquid adhesive directly.
The adhesive is evenly applied to one side of the foam substrate using precision coating heads (such as comma scrapers, micro-embossing, or slit-type coating heads), with the coating thickness precisely controlled at the micron level.
4. Drying and curing in the drying tunnel
The coated wet tape enters a high temperature oven up to tens of meters long.
The curing process is divided into multiple temperature zones, with precise temperature control. During this process, the solvent is completely evaporated (for solvent-based adhesives) or the adhesive undergoes a preliminary cross-linking reaction (for solvent-free adhesives).
Purpose: to form a stable, pure and final adhesive layer.
5. Composite with the first release paper
After coming out of the oven, the semi-cured rubber surface will be immediately pressed with a layer of release paper (or release film).
This layer of release paper is designed to protect the first adhesive surface and prevent it from sticking to other layers when wound.
6. Reverse coating and lamination
Flip the Double Sided Foam Tape 180°, repeat steps 3 to 5, apply and dry on the other side of the foam, and laminate a second layer of release paper.
Key technology: Ensure that the thickness and performance of the two adhesive layers are consistent.
Stage 3: Post-processing and quality control
7. Maturity
The coated large rolls are transferred to an aging chamber where they are left to mature under controlled temperature and time conditions.
Objective: To allow the molecular chains of the adhesive to complete the final cross-linking reaction, so that its properties (such as cohesion, viscosity) reach a stable and optimal state. This is the key to ensure adhesion and durability.
8. Slitting and Re-rolling
The matured mother roll is loaded into the high-speed slitter according to the customer order requirements.
The machine uses a sharp circular blade to cut the wide mother coil into the required narrow width (such as 8mm, 10mm, etc.).
At the same time, the coil is rolled again to control the length and tension of each coil to ensure neat coil shape.
9. Final Inspection and Packaging
The finished products after cutting are inspected for 100% appearance, and the key performance (such as thickness, initial adhesion force, peel force, etc.) is sampled.
Qualified products are labeled with specifications, batch number, length of rice and other information, and then packed against dust and pressure to prepare for warehousing and shipment.

Application Selection Guide:
For lightweight applications (e.g., signage or DIY home projects), 0.3mm-0.8mm's PE foam tape is highly recommended.
Structural bonding (e.g., electronic enclosures, automotive trim): 1.0mm-1.5mm medium-high density PE/PU foam tape is recommended.
For harsh environments (e.g., outdoor, high-temperature, curved surfaces), acrylic foam tape is recommended for its superior weather resistance and durability.
We recommend that you provide our technical team with specific adhesive materials, environmental conditions, and performance requirements. Norpie Packaging will then recommend the most suitable product model and provide free samples for testing and verification.
Q1: How to choose the thickness of double-sided foam tape? Is thicker better?
A: Thicker is not always better. The right thickness depends on your use.
0.3mm-0.5mm: Use this for light jobs. It works on smooth surfaces. It gives little cushion or fill. Good for signs and film switches.
0.8mm-1.5mm: This range works for many uses. It fits electronic assembly, car trims, and home decor. It fills gaps. It gives good cushion.
2.0mm and above: Use this for heavy loads. It works on rough surfaces. It reduces vibration. Good for industrial use.
Our sales team can help you pick the best thickness.
Q2: How is the temperature resistance and durability of this tape? Can it be used outdoors?
A: Yes. Our standard tape works well from -20℃ to 80℃ for long periods. It can handle short bursts of extreme heat or cold. For outdoor use, we suggest UV-resistant tape. This type resists aging. It does not turn yellow or crack in sunlight. It stays stuck outside for a long time.
Q3: How long does it take to reach maximum strength after bonding?
A: The Double Sided Foam Tape sticks right away. You can fix parts quickly. But it takes 24 to 72 hours to become fully strong. Press the surfaces evenly during this time. Do not pull or peel the tape.
Q4: How do I get samples for testing? How long does it take to deliver after ordering?
A: We offer free samples. We want you to test them. Contact us on our website or by email. Tell us the specs and your use. We usually send samples in 1-2 business days.
For delivery, we keep stock for standard sizes. We ship most orders in 3-5 working days. For large orders or custom tapes, we will tell you the delivery time based on production.
