OGD-11A Hot Melt Adhesive for Courier Bag Sealing

OGD-11A is a light-yellow transparent, non-toxic hot melt adhesive in block form, primarily developed for courier bag sealing. It is also suitable for bonding adhesive-backed bags, paper products, metal, plastic, and nonwoven fabrics.

With a melt viscosity of 5,300 cps at 170°C and a Ring and Ball Softening Point of 73°C, OGD-11A provides an initial tack of >18# copper ball and a peel strength of >15 N/in. The recommended operating temperature is 165–180°C.

The adhesive offers strong initial adhesion and cohesive strength, with minimal stringing during coating and good resistance to oil penetration. It is supplied with white release paper and is compatible with transfer coating production lines. During processing, the adhesive can be transferred from the release liner onto the courier bag surface to form a tamper-evident sealing layer. Once opened, the sealed area is designed to show visible damage, helping prevent unauthorized opening and resealing of parcels.

Description

Precautions

01. Temperature Control
Do not operate continuously above 180°C for extended periods, as prolonged exposure to high temperatures may accelerate adhesive aging and affect tamper-evident sealing performance.

02. Remove the Release Paper Before Melting
Remove the outer white release paper before feeding the adhesive into the melting tank. Do not place the release paper into the tank, as foreign material may cause nozzle or coating equipment blockage.

03. Adjust Temperature According to Line Speed
Fine-tune the application temperature according to the coating machine's operating speed to maintain smooth and consistent adhesive transfer.

04. Allow Sufficient Cooling Before Rewinding
After coating and lamination, allow the adhesive layer to cool and set sufficiently before rewinding to help prevent adhesive layer displacement and poor transfer.

05. Refer to the MSDS
Store this adhesive separately from other hot melt adhesive grades to prevent accidental mixing or misuse.

Key Benefits

01. Tamper-Evident Sealing for Courier Bags
Balanced cohesive strength allows the adhesive layer to undergo cohesive failure when the bag is opened, making complete resealing difficult and supporting tamper-evident packaging applications.

02.Enhanced Heat Resistance for Warm Storage Conditions
Compared with conventional courier bag hot melt adhesives, OGD-11A provides improved heat resistance and helps maintain sealing performance under elevated storage and transportation temperatures.

03. High Initial Tack for Fast Bonding
With an initial tack of >18# copper ball, the adhesive provides quick positioning and setting after application, supporting high-speed courier bag production.

04. Smooth Coating with Minimal Stringing
Stable melt flow and leveling performance help minimize stringing during high-speed coating, contributing to a cleaner bag surface and consistent application quality.

05. Good Resistance to Oil and Grease Penetration
Provides resistance to oil and grease penetration, helping maintain sealing performance when packages are exposed to limited amounts of oily substances.

06. Multi-Substrate Compatibility for Flexible Production
In addition to PE courier bags, the adhesive can be used for bonding paper, plastics, nonwoven fabrics, and metal components, supporting a wider range of packaging applications.

Material

Tamper-Evident Sealing: A hot melt adhesive system designed for destructive sealing of packaging. Its balanced cohesive strength allows the adhesive layer to undergo cohesive failure when opened, making complete resealing difficult.
Heat and Oil Resistance: Provides higher heat resistance than conventional courier bag hot melt adhesives, together with good resistance to oil and grease penetration, supporting packaging storage and transportation under warm conditions.
Stable Transfer Coating: Provides smooth and consistent transfer coating performance for efficient application on courier bag production lines.

Storage Condition

Store the adhesive blocks with release paper in a cool, dry, well-ventilated warehouse away from heating equipment to prevent softening and sticking caused by heat. Stack the blocks flat and avoid heavy loads that may cause deformation. Protect the material from dust and contamination. Shelf life: 12 months.
