Products Description
Hiknuo Hinged Wedge Sandwich Containers. Snap the lid on and nothing gets squashed; pick it up and nothing rattles around. In a chilled display case, customers can see the whole product through the crystal-clear walls at a glance. Compared to square boxes, it barely wastes any space - it stacks and travels more efficiently too. That's why most retail customers doing short-shelf-life sandwiches in Europe and the US basically lock onto this box shape.
There are two structural options: the one-piece hinged box is the fastest to pack, while the two-piece tray-plus-flat-lid version stacks. Sizes cover the US-style 6.5″ × 3″ × 3.25″ and the UK-style 180 mm standard / tall / 3-pack versions.
