Continuous feed storage envelopes

Abstract

A plurality of continuous feed storage envelopes are connected in a strip formed by a seal flap layer of glassine overlying a base layer of paper material. Connected envelopes are fed through a machine that cuts individual negative frames from a roll of developed film for insertion in the compartments of the envelopes. The envelopes are separated from one another in the series by tear lines. The lower edge of each envelope is sealed by a glue line. Extending transversely between the overlying layers are parallel spaced glue lines that form the lateral margins of each envelope. At one lateral margin the glue line extends the entire length of the envelope. At the opposite margin the glue line has a shortened length so that a portion of the overlying layers along one margin are not adhesively secured. When the envelopes are connected in the series, both lateral margins of each envelope remain sealed by the tear lines. When an envelope is separated from the series of connected envelopes, the tear line at the margin having the shortened glue line is severed so that the portion of the seal flap positioned above the top of the shortened glue line is released from the base layer at the margin down to the glue line. In this manner, the opening into the envelope compartment is expanded to facilitate ease of insertion and removal of the negative and the negative mounted on an aperture card.
