Calibration of the oxygen sensor of headspace gas analyzer LTDK-190
Therefore, it is particularly necessary to strengthen the rubber airbag to test the gas barrier performance of filling.
Oil seepage often occurs on the surface of some meat product packaging bags with high liquid oil content.
PET bottles are usually modified, such as by coating silicon oxide and amorphous carbon on the surface of PET bottles. Therefore, before beverage manufacturers choose and use PET bottles, it is essential to test their moisture barrier properties.
Brief instruction of cobb absorption tester LTBXS-01
Why do pickled vegetables become rancid, mildewed, and swollen? What properties should be focused on when inspecting the material of instant coffee packaging? What are the common packaging forms of instant coffee?
The level of this peel strength directly affects the overall oxygen transmission rate, water vapor transmission rate, impact resistance, puncture resistance and other physical and mechanical properties of the material.
Therefore, the detection and control of the friction coefficient of polyethylene shrink film is an effective way to improve its performance, and it is also a basic requirement of the standard.
Monitoring the residual oxygen and carbon dioxide content in the packaging is not only one of the effective means to ensure the good quality of drugs, but also a basis for determining the shelf life.
If the packaging is poorly sealed, potato chips will easily become soft during storage and sales. Therefore, potato chips The packaging bag should have good sealing performance. In this paper, the principle of negative pressure method is used to test the sealing performance of shrimp cracker packaging.
Therefore, it is necessary to strengthen the detection of moisture-proof performance of instant noodle packaging.
It can simulate the behaviors of rubbing, folding and crushing damage of the film during production, processing, transportation, etc.
