Setup, Compatibility & Care
To ensure proper function, keep the stack of envelopes in a cool, dry place to prevent the gummed strips from activating prematurely due to humidity. When loading into a mailing machine, fan the stack lightly before insertion to ensure the machine can separate them easily. Because the closure is gummed, verify that your automatic inserter or sealing machine has the water reservoir filled and correctly adjusted to apply the right amount of moisture. Do not store these in direct sunlight, as the manilla paper may fade or the adhesive may degrade over extended periods.
