Hot Melt Adhesives

Hot Melt Adhesives

These adhesives in film form bond completely different materials together. The layer thickness is uniform, and durability is long lasting. We can add chemical and heat resistance as necessary, and freely adjust film thickness.

Meta seal®

This Hot melt adhesives in film form bond completely different materials together. The coating technology we have cultivated over many years enables us to adhere to materials that are easily peeled off such as fluorinated films. As this is a film form of hot-melt adhesive, it improves processing efficiency for bonding the adherend in a short time.

Features

Adhesion to different materials

Different materials can be bonded together as described below.

  • Metal: SUS, aluminum, nickel, titanium, etc.
  • Ceramics: Glass, gypsum, fine ceramics, etc.
  • Film: PP, PET, nylon, fluoride, etc.
Uniform thickness by precision coating

Meta Seal® is a film that is precise coated with hot melt adhesive, so it has a layer thickness that is more uniform than liquid or paste, and there is no unevenness in adhesion force or application.

Long-lasting

This boasts high durability against chemical (acidity and alkalinity) and hydrolysis, and it works for a long time.

Customizable

The thickness, antistatic function, and more can be customized.

Improved durability
  • Chemical resistance
  • Heat resistance
  • High elasticity
  • Thickness
  • Cuing temperature (90℃-)
  • Delivery form (tape, roll, punched product)

Example Applications

Automotive field
  • Automotive exterior and interior
  • Tire parts
Energy field
  • Battery sealing
  • Fuel cell separators, etc.
Electrical and electronic fields
  • Electronic components (HDD, sensors, RFID tags, etc.)

Tab Seal film

Tab Seal film is a Hot Melt adhesive for tab leads of lithium-ion batteries with electrolyte-resistance, which was developed through the application of Meta seal®, an adhesive for different materials. It is a highly reliable film with a proven track record of over 20 years.

Product Features

long-lasting

Heat sealing provides excellent adhesion to metal tabs and outer bags. Tab seal can be used for a long time by minimizing the deterioration of adhesion force after immersion in electrolytic.

Provides both insulation and flexibility

Since the core layer and adhesive layer are laminated, Tab seal has both insulation and flexibility, and reduces sealing failures after heat sealing process.

Heat sealing performance

This allows bonding over a wide range of temperatures, contributing to greater freedom in manufacturing design and process efficiency.

Example Use

Double-sided Metal Adhesion Type

This type can be bonded to any adhesive surface.

Single-sided Metal Adhesion Type

This has firm adhesion to aluminum pouches in addition to the above.
