Glue stick coating of solid glue, paste, timeliness, flexibility, technical problems:
Coating requirements: return on paper coating, feel relaxed, smooth, glue large, obvious traces.
Paste requirements: A4 copy paper in a single coating flatten off after 1 minute tear, paste side to be torn hair or tear.
Timeliness requirements: Glue stick, the shelf life of 18 months or less should be no significant variation characteristics.
Flexibility requirements: plastic bottles, twist up and down the bottom of the knob should be freely and easily.
Heat test: 50 ± 3 ? 24 hours after the weight loss rate of less than 0.8%
Cold test: -15 ± 3 ? 24 hours after the viscosity requirement is consistent with the paste.

Current problems: Paste is very good, that is, faster dry rubber surface, even in the case of the lid sealed. The first time feel under heavy coated paper; good if sticky adhesive rod, and low temperatures in winter, the plastic bottle at the bottom of the knob on the screw fixed. Plastic bottle at the bottom of the knob can be moved twisted, Glue stick the adhesive on the poor. Glue stick there longer shelf life, the more dry plastic surface.
