SOS Bag (Self Opening Sack)

Provide the largest item footprint, total load and packing sequence. Trial the opened square base with real contents and check whether tall or narrow items make the sack unstable. Choose the usable opening and base dimensions around the order rather than the folded bag size.

Specify condensation and possible leakage before selecting the paper construction. Trial the packed sack under relevant conditions and inspect the base and side seams. Do not assume a grocery format or natural kraft appearance establishes wet strength or direct food-contact suitability.

Confirm the exact construction on the approved drawing; self-opening describes the opening and base format rather than a handle specification. If handles are required, state their type and intended carrying load. Evaluate the completed bag with its actual contents before assigning a carrying claim.

Ask operators to open, fill and hand over samples using the normal checkout sequence. Inspect base opening, rim tearing and awkward item placement. Record the approved paper grade and dimensions so a bag that looks similar when flat is not substituted without review.
