To attain this grade, the front of the card should display centering of 60/40 or better, while the back must exhibit centering of 90/10 or better. 10 - Gem Mint (GEM-MT) - The card features impeccably sharp corners, retaining its original gloss in full. The card's focus is sharp, and it is devoid of any staining.
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
The child-resistant locking closure for containers was invented in 1967 by Dr. Henri Breault. [7]A history of accidents involving children opening household packaging and ingesting the contents led the United States Congress to pass the Poison Prevention Packaging Act of 1970, authored by U.S. Senator Frank E.

This represented a reduction in the rate of fatalities, up to 45%, from projections of deaths without the presence of child-proof packaging and equated to an average of 24 fewer deaths in children annually.

Pressure-sensitive tape or pressure-sensitive adhesive tape (PSA tape) is an adhesive tape that sticks when pressure is applied without the need for a solvent (such as water) or heat for activation. It is also known in various countries as self-stick tape , sticky tape , or just adhesive tape and tape , as well as genericized trademarks , such ...
The pressure applied to the tape allows the tape to have better contact with the surface and allows the physical forces between the two to build up. Usually, increased application pressure increases the bond of the adhesive to the substrate. PSA tape laboratory testing is often conducted with a 2 kg roller to increase test uniformity. [13]
