Labelmaster's full line of bottle caps fit on glass or poly bottles of all shapes and sizes. To determine the cap material, consider the contents' chemical compatibility, dispensing/storage requirements and transportation regulations (if applicable).
Next, match the mouth size of bottle and cap. Each cap size is shown as two units (e.g., 22/400). The first number is the mouth size (bottle opening), and the second number is the bottle thread dimension. Be certain that the mouth of the cap matches that of the bottle.
Finally, be sure to choose the proper closure for the bottle, which is determined by compatibility and mouth size.
Labelmaster offers free samples of caps to make sure you order the correct size and material before you place your order.
