Closable sack - has hole(s) in closure flap covered on back by self-adhesive strip

摘要

Closable envelope-type sack or sachet pref. mfd. from plastics film for use in packaging, has >=1 hole in the closure liq covered on the back by a permanently self-adherent strip in such a way that in the folded-over state of the closure liq. the adhesive face of the adhesive strip sticks to the sack through the holes so as to close the sack. Overcomes the problem of elasticity of plastics film which causes the folded over liq. to return to its unfolded state, without the need for costly fasteners.
