Abstract: An exemplary molding method may include converting plastic wrap into moldable plastic, loading the plastic into a mold, and molding the plastic into a desired product. The method may also include cleaning and/or shredding the plastic wrap. An exemplary molding system may include a plasticizing apparatus and a mold. The plasticizing apparatus may be configured to convert plastic wrap into moldable plastic. The plastic may be loaded from the plasticizing apparatus to the mold, which may be used to mold the plastic into a desired product. The molding system may also include a cleaning apparatus and/or a shredding apparatus.

Abstract: A structure such as a table-tennis top or a table top may include a first portion and a second portion. The first portion may be constructed from blow-molded plastic and include a hollow interior portion that is formed during the blow-molding process. The first portion may also have a first set of characteristics such as lightweight. The second portion may be attached to the first portion and the second portion preferably has a second set of characteristics that are different than the first set of characteristics of the first portion. For example, the second portion may have increased mass relative to the first portion. The different characteristics may allow a structure such as a table-tennis top or table top to be constructed with desired characteristics.
