All corrugated cardboard has a layer of corrugated fluting and at least one liner. Fluting and liners can be combined in different layers to create different types.
In order to measure the bursting strength of a corrugated box – or how many pounds of pressure it would take to rupture the material – we use the Mullen Test. Corrugated boxes will be labeled with 200 #, 275 #, 350 #, etc. The higher the number, the more durable the box will be. 200 # indicates that the box can withstand pressure of up to 200 lbs per square inch before bursting.

Most Common Types of Folding Carton:
Rigid boxes consist of basically two parts – a lid and base. The shapes and sizes of rigid boxes vary greatly – square, rectangular, circular, etc. But in the packaging industry rigid box styles are usually categorized and described by the type of lid used.
Full Telescope Lid: lid covers the entire base of the box, e.g. chocolate and candy boxes
Partial Telescope Lid: lid covers part of the base of the box
Classic Shoebox Lid: lid has a lip that is traditionally 1 inch deep
Hinged Lid: lid is attached permanently and stays closed using gravitational forces or with a magnetic strip or a ribbon binding – these boxes are great for frequent-use products that are meant to be stored in their packaging in-between uses

Bioplastic (plant-based plastic)
Edible Cellophane Wrappers are largely made from starch, but can also be made from milk protein. They can be consumed with the food and they give you the opportunity to add vitamins, minerals, and even flavors by embedding them in the film.
Molded Pulp is recyclable, compostable and biodegradable. It is made by combining water and recycled paper, most often kraft off-cuts, recycled newspaper or a combination of both, which are then heated to give strength and rigidity.
Compostable Packaging is packaging which is manufactured from renewable plant-based materials and has been certified to compost within an industrial composting process to fertilize the soil, along with food and garden waste.
