成形パルプ製 18個入り卵パック

It depends on the municipality rather than the product. Molded pulp egg cartons are made from short recycled fibers that have already been through several cycles, so some paper streams accept them and others direct them to compost. The carton composts in a home pile regardless. We advise printing a disposal instruction that matches your primary market.

Compression testing on a filled carton under progressive load until deformation, reported as the load at first structural failure. The figure only means something alongside the test method, the conditioning humidity, and whether the carton was tested filled or empty. We report all four, and we recommend asking any supplier for the same.

 A flat top gives a better print surface and stacks marginally tighter, but it needs the reinforcing rib to be deeper to compensate for the lost arch strength. We tool flat top eighteen counts as a custom mold rather than stock, so allow additional lead time.

It uses more material per egg than you might expect, because the reinforcing structure adds fiber that a twelve count does not need. It also prints at a higher cost per unit and nests slightly less efficiently. The packaging cost per egg is usually modest but it is not lower than a dozen, which surprises buyers who assume bulk always wins.

In most US refrigerators, yes, which is a large part of why the format sells. The carton runs about 305 mm long and 155 mm wide, which clears typical door bin dimensions. Compact and apartment sized refrigerators are the exception, and buyers targeting urban markets sometimes prefer two dozens for that reason.
