Test Range

Testing Items

Obstructing performance

For consumers, the most common food safety problems mainly include oxidative rancidity, mildew, dampness or dehydration, odor or aroma or flavor loss, etc. The main detection indexes include: organic gas permeability, high and low temperature gas permeability of packaging film, oxygen permeability, carbon dioxide gas permeability, nitrogen permeability, air permeability, flammable and explosive gas permeability, oxygen permeability of container, water vapor permeability, etc

Mechanical capacity

Physical and mechanical properties are the basic indexes to measure the protection of packaging contents in production, transportation, shelf display and use, including the following indexes: Tensile strength and elongation, peel strength, thermal bonding strength, impact strength of pendulum, impact strength of falling ball, impact strength of falling dart, puncture strength, tear strength, rubbing resistance, friction coefficient, cooking test, packaging sealing performance, light transmittance, fog, etc.

Hygienic property

Now consumers are paying more and more attention to food hygiene and safety, and domestic food safety problems are emerging in an endless stream, and the hygiene performance of packaging materials can not be ignored. The main indicators are: solvent residue, ortho plasticizer, heavy metals, compatibility, potassium permanganate consumption.

The cushioning property of the cushioning material

Dynamic shock, static pressure, vibration transmissibility, permanent deformation.
