Plastic Bottle Manufacturer-Reducing Odor In Plastic Bottles: What Are They?

Plastic is an important raw material in the cosmetic packaging bottle industry. Plastic processed products emit unpleasant odors. In order to overcome this problem, plastic resin producers and processors have been working for a long time to reduce the level of these odors. The solutions are: use low-odor alternatives to replace those unpleasant additives; reduce the amount of residual monomers in plastics; add gas adsorbents and antibacterials to plastics to prevent the occurrence of difficult problems caused by bacteria and fungi Smell the odor; and the residual odor can be reduced by solvent extraction and exhaust during the processing of recycled plastic.

 

  Plastic bottle manufacturers also treat plastic particles with special detergent solutions that can also help remove odors. Generally these detergents are aqueous or alkaline solutions containing surfactants. These cleaners can effectively remove vinyl chloride monomers, styrene, acrylates, acrylic monomers and unsaturated hydrocarbons.


The first step in objectively identifying odors is for a group of people to distinguish whether the smell they smell is pleasant or unpleasant. According to the response of the discrimination team, standard instrumental analysis methods such as meteorological chromatography and solid-state spectroscopy (GS / MS) were used to determine the level of plastic volatiles. However, these earlier instrumental analysis systems require careful analysis and evaluation by experts in order to draw accurate conclusions. The new plastic odor detection device is a device that becomes an "electronic nose", which relies on electronic probe dot matrix and pattern recognition technology to work. The instrument operator guides the released volatiles into the probe dot matrix for detection by heating the sample. The obtained results are displayed in digital mode, so it is easy to correlate with the conclusions of the discrimination group. According to specific requirements, the volatile odor can be classified as pleasant, neutral, unpleasant, or reported in the form of intensity and molecular aggregation.

 

  Waste plastic tends to have a bad smell. Most recycled plastic packaging, such as hdpe, pp, pvc, and pet, will be washed in aqueous solution to remove contaminants. But the odor absorbed inside the plastic will still remain. Organic solvent extraction helps remove odorous compounds. A new solvent extraction method also uses supercritical carbon dioxide as a solvent. This technology has been applied to hdpe and pet, and it can remove odorous pollutants from oil containers, pesticide containers and other used devices. The advantage of the carbon dioxide extraction agent is that it does not cause troublesome post-treatment problems of organic solvents.

 

The odor removal device is an integral part of the waste plastic pellet extruder, and it can also effectively remove some volatile strong volatile compounds.
