「MGE700」；Good for Workability and Beautiful Finishing Type「MGZ702」；Standard Type
「MGE700」；Good for Workability and Beautiful Finishing TypeMitsui Masking Tape™ MGZ702, MGZ700 are superior surface protective film consisting of special polyethylene film with water based acrylic adhesive.
Features
- Lamination:Easy and silent unwinding on lamination process with adherend
- Processing:Beautiful cutting edge and low brunt in fiber laser processing.
- Peeling：Easy and silent removal at fast speed from adherend
- Environment ：We use water based acrylic adhesive materials (no solvent).
It’s environment-friendly (reduce CO2 and solvent emission during tape
Recommended applications
Surface Protection for Stainless steel and aluminum plates in fiber laser process.
We recommend to test lamination and laser processing for evaluation.

- ・Method of Adhesive Strength Measurement ：180° peeling method: peeling speed 300 mm/min, Adherend: SUS304 BA・2B・HL plate.
- ・Method of Rewinding Strength ： peeling speed 300 mm/min from roll,
- ・These values are for reference only based on the results of our laboratory tests, is not guaranteed.
- ・The unit above are SI unit. If you would like to convert the unit of adhesive strength and unwinding force into CGS units (g/25mm), please multiply it by 100.

- Measure：
- 50mmwidth、peeled by 2m/min speed, length 20cm
- ＊These values are typical ones based on the results of our laboratory tests, not guaranteed ones.
- ・The small unwinding force allows for easy and silent unwinding.
- ・Compared with competitors, it can contribute the ‘Kaizen’ in the working environment.

Data of peeling force
【Adhesive strength changes depends on peel speed】
- ＊Measured in 10 days after lamination , 23℃
- ＊These values are for reference only based on the results of our laboratory tests, is not guaranteed.
- ・The biggest improvement for easy peeling can be seen in ‘SUS-2B’ stainless plate.
- ・For ‘SUS-HL’’ and ‘SUS-#400’ plates, the moderate improvement can be seen as well.
