What are a few factors to consider when choosing envelope adhesives?

Here are key factors to consider when choosing the suitable envelope adhesive.

Envelope and Flap Material:

• Paper type: Different papers have differing absorbency levels, involving drying time and bond strength. Therefore, consider adhesives that work well with the specific paper type (e.g., kraft paper, glossy photo paper).
• Flap weight and thickness: For heavier or thicker flaps, you require stronger adhesives to ensure a secure seal and should opt for a denser adhesive for heavier envelopes.

Application and Usage:

• Sealing speed: Pick an adhesive with a drying time that fits your needs. Opt for fast-setting options for high-volume mailing or slower-drying glues for specific applications.
• Storage conditions: If envelopes are kept for a while before use, choose adhesives with good shelf life and resistance to temperature and humidity extremes.

Environmental Considerations:

• Temperature: Will the envelopes be exposed to harsh temperatures? Choose adhesives that hold their sealing ability in hot or cold environments.
• Moisture resistance: If envelopes undergo moisture (rain, humidity), prioritize adhesives with good water resistance to deter the seal from weakening.
