A packaging tray for holding a tube-type container having a tube body with a cap for sealing contents in the tube body on one end and a crimped tube portion on another end. The packaging tray including: a folded body formed of paper board, the folded body having a top surface having a first aperture configured to accommodate and retain the tube-type container therein. The folded body having a tube crimp support at a first end of the first aperture, the tube crimp support being configured to secure the crimped tube portion in the first aperture, the tube crimp support comprising first, second and third layers, the first layer having the top surface, the second layer being sandwiched between the first and third layers, and the second layer having a first end comprising a first stop for preventing the crimped tube portion disposed between the first and third layers from moving longitudinally in a first direction within the first aperture.

Recyclable Hemp Composition and Uses in Container Manufacturing
20220411154 · 2022-12-29 ·

The present invention relates to a cardboard container made from three layers including recyclable hemp paper. The hemp paper has a novel composition comprised of hemp infused pulp, hemp strands, and hemp fiber to add reinforced strength. The three layers include an outer liner of hemp paper, a wavy layer of the hemp paper, and an inner layer of plane hemp paper. The cardboard box is configured to replace conventional tree paper containers or boxes and can be made in various shapes and sizes. The hemp paper composition reduces the number of trees being cut down and landfill waste due to non-recyclable materials being thrown away. The container of the present invention can be recycled and provides an environmentally conscious option for users.
