Exclusive 100% Risk Free Quality Guarantee
If we test your fabric / membrane and recommend a seam tape that fails to perform as we promised, when applied according to our recommended conditions we will replace that seam tape at no charge to you, including freight. All we ask is that you return the unused portion to us at our expense.
We will ask that you send us a sample of the fabric related to the problem with tape applied for our testing prior to replacement. This enables us to determine what caused the failure so that we may correct it for future customers
For more than 20 years, HiMEL has been developing and manufacturing a wide range of tapes and adhesives for use with seam sealing. We’ve combined this experience with the latest machinery and new chemistries to bring our customers high-quality products designed to match their needs.

QUALITY CONTROL PROCESS
Thorough Quality control process
HiMEL’s seam tapes are being tested at it’s laboratory before ex-factory
01. Hydrostatic test
Tested model No.
Pressure / Dwell time
3 psi / 2minutes
Washing condition : Machine wash at 40° for 10 cycles line dry (washing machine model no. SEW-HW1065)
02. PEEL STRENGTH test
Tested model No.
Test using multi test 2.5d by Mecmesin made in United Kingdom (unit: kgs)
which means it has uniform strength
03. TAPE MARK test
Recently it is the tendency to adapt very light weight fabrics for the outdoor wears and it requires more care in seam sealing process. When it happens in the garment factory you may could,
A) Lower the seam sealing temperature
B) Lower the roller pressure
But it may be also caused by the heat from the seam sealing machine, the pressure of the roller, the difference between the tape material and fabric coating.
Using pucker free seam tape, you can prevent from tape mark on your garments.
04. WASHABILITY test
Separation of seam tapes is caused often after wash. It is called “hydrolyzed”generally. When it happens in the garment factory you may could,
A) Lower the seam sealing speed
B) Higher the seam sealing temperature
C) Clean the contaminated fabric with solvent
But it may be also caused by lack of endurance of seam tape’s adhesive against the water temperature and frictional force of washing machine during the washing.
Using seam tape which has excellent washability, you can prevent from hydrolyze
05. MICROSCOPE test

Surface of good tape
Adhesive (brown part) is applied evenly on all the surface of film which indicates strong adhesive power.
*specimen : HiMEL S330
Surface of bad tape “A”
Lots of blisters (white part) are shown on the surface of film which indicates adhesive is applied unevenly and cause weak adhesive power.
*specimen : Tape from company “A”
Surface of bad tape “B”
Lumps of adhesive (brown part) are shown on the surface of film which indicates adhesive is applied unevenly and cause weak adhesive power
*specimen : Tape from company “B”
06. TEMPERATURE AND HUMIDITY test
As a final process of lab test, we are doing “Temperature & Humidity” test. Many of our customers factories located in the hot areas like Vietnam, Indonesia and Bangladesh where the temperature gets high up to 40°C in summer with 95% humidity.
On the contrary, our tapes could be used in the cold temperature, too. Under those harsh conditions seam sealing doesn’t going smoothly sometimes.
By letting our tapes in those circumstances, we could see what’s going on and prevent the possible problems in advance.
