solvent residual solvent residual composite packaging generally produced in the printing ink, solvent and the production process, the commonly used solvents such as toluene and butanone, ethyl acetate.
1988 complex compounds, itself is neither decomposition, digestion and absorption in the body also is not, and therefore is considered to be a safe, non-toxic packing material.
but due to the need of processing, in which often join a variety of additives, such as promoting agent, protective agent, filling agent, bring food safety problems.
Synthetic rubber is mainly derived from oil chemical raw materials, sort is more, is composed of monomer through various processes of polymer compounds, free small molecules are harmful to human body.
