Switching Packaging Adhesives to Techbond: Evaluation and Trial

When switching packaging adhesives to Techbond, assess the substrates, equipment, bond requirements and production-line trial results. Do not select a replacement solely by brand or price per kilogram. The adhesive must meet finished-product quality, operating conditions and actual cost-in-use requirements.

Techbond Vietnam manufactures industrial adhesives in Vietnam and supplies solutions for paper, packaging and other industries.

When should packaging adhesive be reassessed?

Consider an evaluation when changing paper, board or coatings, increasing line speed, experiencing open edges, changing storage conditions or seeking another supply option. Each change can affect adhesion and working time.

Before changing adhesive, check application amount, nozzle or roller condition, compression time and substrate quality. A bond failure does not always originate in the adhesive.

Information needed for a replacement recommendation

• Materials: paper, board, coating and both bonding surfaces.
• Process: carton sealing, box making, lamination or another specific operation.
• Equipment: application method, machine speed, compression time and operating conditions.
• Quality: strength, appearance, current defects and testing method.
• Environment: expected temperature, humidity, storage and transport.
• Supply: consumption, pack size and delivery schedule.

Provide the current adhesive TDS, SDS and operating parameters when available. These documents establish initial requirements but do not prove direct equivalence or interchangeability.

Comparing hot melt and water-based adhesives

Aspect	Hot melt	Water-based
Mechanism	Conventional thermoplastic hot melt is heated for application and bonds as it cools.	Water leaves the adhesive layer; the mechanism depends on the formulation.
Operating checks	Application temperature, open time, compression and feeding equipment.	Surface absorbency, coating amount, drying and compression.
Trial criteria	Edge hold, strength after storage, glue marks and operation.	Adhesion, drying, appearance and substrate shape.

These groups have different equipment and operating requirements. Assess the line before changing adhesive technology.

Four steps to trial a packaging adhesive

1. Record current performance

Record substrates, consumption, machine speed, application conditions and defect rate as a baseline.

2. Confirm documents and trial plan

Review the correct product TDS, SDS and instructions. Agree acceptance criteria, inspection times and sample storage conditions. Confirm cleaning and compatibility procedures; do not mix new adhesive with residue in equipment without guidance.

3. Test on actual materials and equipment

Run the trial according to instructions and record settings and consumption. Check initial adhesion, strength after conditioning and appearance. Include heat, cold or humidity where relevant to actual use.

4. Evaluate before rollout

Compare quality, operation, consumption and defects. Expand only after agreed criteria are met and supply conditions are clear. Retain records for future material or line changes.

Compare adhesive cost per product

Adhesive cost per product = average adhesive consumption × unit price on the same basis. Total process cost can also include energy, labour, cleaning, rejects and relevant downtime.

Compare quotations on the same order quantity, packaging, tax, transport and delivery terms, and compare products meeting the same application and quality criteria. Savings can only be established from actual usage and trials.

Frequently asked questions

Can Techbond replace the current packaging adhesive immediately?

Do not switch before reviewing documentation and testing. Confirm substrates, equipment, cleaning and quality criteria first.

Is Techbond adhesive completely equivalent to another brand?

Equivalence cannot be established from brand or technology alone. Evaluate each product, substrate and operating condition using technical documents and trials.

What should be checked for food packaging?

Specify the packaging structure, adhesive location, potential food contact and destination market. Confirm the appropriate documentation for each product and application.

Does a lower unit price reduce cost?

Not necessarily. Consider consumption, energy, defects and downtime alongside bond quality.
