LDPE Boston rounds are the perfect solution for liquid sample handling in a squeezable bottle.

 

Attached black thermoset (phenolic) caps with pulp and vinyl liners are perfect for general use. The liner is made of a vinyl coating applied to high density polyethylene coated paper and then it is laminated to pulpboard. This general purpose liner is commonly used for food, beverage, medical and chemical applications packed at less than 120 degrees Fahrenheit.
