There are several types of closure for your envelopes and pouches that will optimize your shipments.
The gummed legs:
This is often the most economical solution. It allows a manual insertion but also automatic insertion. To close the envelopes with gummed tabs, it is sufficient to moisten the strip of adhesive deposited on the closure tab and fix it by pressure. Attention to the conservation of the closing system of the envelopes with gummed legs which is only 1 year.
This solution is the fastest and ready to use. It is suitable for one-off shipments or for pre-printed envelopes and stored before use. To close this type of envelope, a pressure on the flaps is enough. These envelopes are stored away from moisture, heat and dust. The conservation of the closure system is 2 years.
Self-adhesive tabs with protection tape:
This is the easiest, fastest and most effective method. Perfect for daily shipments, the envelope closes by taking off the paper protection and folding the tab. Attention, the conservation of the closing system is also about 2 years.
