OBT (6" x 9") Laminating Pouches

This format can suit photographs, notices, certificates, reference cards, signs, instructions, and other medium-sized printed pieces that need more room than an index card but less than a letter sheet. The deciding factor should be the actual insert dimensions and how the item will be used after lamination. Consider whether it must fit a frame, holder, display stand, binder pocket, or storage tray. Also allow for any border required around the artwork. A physical mockup is useful when the item will be mounted or inserted into another product. The pouch should support the final use without requiring so much trimming that the sealed edge becomes narrow or uneven.

Choose thickness according to the flexibility, rigidity, and handling resistance the finished piece needs. A thinner film keeps the item more flexible, while heavier film gives signs, cards, and frequently handled materials more body. The options within laminating pouches by thickness should also be matched to the maximum capacity of the laminator. Remember that the stated thickness normally applies to each film side, so the completed item includes both layers and the insert. A heavier pouch is not automatically better if the piece must bend, fit a holder, or pass through a machine with a lower thickness limit. Test a finished sample in its holder or display position before committing to the full quantity.

Leave enough clear film for the adhesive layers to bond directly to each other around every edge. Cutting flush with the paper removes that protective seal and can allow moisture, dirt, or separation to reach the insert. The ideal border depends on the finished appearance and whether the piece will be trimmed, mounted, or handled often. Keep the insert centered before feeding and allow the laminated piece to cool flat before cutting. Rounded corners may reduce sharp points on frequently handled items, but trimming should never enter the paper edge. Produce one sample and test it in the intended holder or display before setting the trim dimensions for the full job.

The machine must accept the pouch width and the selected film thickness, with heat settings suitable for the adhesive. The range of pouch laminators includes machines with different entry widths and maximum thickness capacities. Feed the sealed edge first unless the equipment instructions specify another method, and use a carrier when recommended for the machine or pouch. A pouch inserted at an angle can wrinkle or leave an uneven border. Allow the laminator to reach its operating temperature, then test one item for clarity, full edge bonding, curl, and surface waves. Record the successful setting when the same materials will be produced again.
