Product Description
Auto lock boxes, also called crash-lock bottom boxes, have a pre-glued bottom that locks into place as soon as the box is opened. Packers push the flat carton open and the base forms itself, so they are much faster to pack than tuck-bottom boxes and carry more weight. The locked base also supports glass and liquids better than a tucked bottom.
Sizes and dimensions
Auto lock boxes are made to your product's dimensions and work best for upright, heavier items. Example sizes: - 3 × 3 × 6 in for bottles, jars and candles - 4 × 4 × 8 in for wine accessories and tall cosmetics - 6 × 4 × 10 in for kits and heavier retail products
Materials and board options
SBS paperboard in a heavier caliper suits most auto lock cartons. For heavier products or boxes that ship on their own, E-flute corrugated adds strength. Kraft paperboard suits natural and eco-focused brands. Auto lock cartons ship flat like any folding carton, so you get the speed of a pre-formed base without paying to ship or store assembled boxes.
Printing and finishes
All four sides and the top tuck can be printed, so the box works on a shelf from any angle. Gloss or matte lamination protects the print; foil and spot UV add highlights. A window or hang tab can be added for retail display.
Common uses
Typical uses: - Bottles, jars and candles - Wine and spirits accessories - Heavier cosmetics and haircare - Kits packed on fast production lines - Food and supplement containers
Is this the right box for you?
Choose auto lock boxes for heavier retail products, glass containers and fast packing lines. For light products, a standard tuck-end carton such as a roll end tuck front box is cheaper. For shipping straight to customers, see custom mailer boxes. More styles: retail display.
