The container compression test measures the compressive strength of packages such as boxes, drums, and cans. It usually provides a plot of deformation vs compressive force . It is commonly used to evaluate shipping containers made of corrugated fiberboard as well as wooden boxes and crates .
Tests are conducted to measure the resistance of packages and products to controlled laboratory shock and impact. Testing also determines the effectiveness of package cushioning to isolate fragile products from shock. Instrumentation is used to measure the shock transmitted to a cushioned product. Simple drop tests can be used for evaluations.
The tape is most often used as a closure for regular slotted containers (RSCs). A "single strip" or "center seam" closure is applied over the center seams of a box extending 50 to 75 millimetres (2 to 3 in) onto the end panels. The tape can be used as a "six-strip" closure or "H-seal" by applying cross strips on the ends of the box.
The strength and adhesive bonding are important. Security labels are usually only used for their security features; backing strength is less important but the bonding characteristics are critical. Some security tapes have an appearance similar to standard packaging tapes to help conceal the value of an item.
A hermetic seal is any type of sealing that makes a given object airtight (preventing the passage of air, oxygen, or other gases).The term originally applied to airtight glass containers but, as technology advanced, it applied to a larger category of materials, including metals, rubber, and plastics.
The adhesive is coated onto a flexible material (the backing) such as paper, foil, fabric, or plastic film (such as biaxially oriented polypropylene or polyvinyl chloride [6] [9]) to provide strength and protect the adhesive from degradation by environmental factors including humidity, temperature, and ultraviolet light. Backing tensile ...
Take a second to look at the plastic cups stashed in your cabinets for a future backyard party. You’ll notice several lines on each 16 oz. cup. ... Moving up, the next line, measuring 5 ounces ...
The edge crush test is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated board.It gives information on the ability of a particular board construction to resist crushing.
