How to deal with the smell of cosmetic packaging materials

If cosmetic packaging materials have odor, you can take the following measures to solve it:

一、Analyze the source of odor

First, the source of the odor needs to be identified. The odor of cosmetic packaging materials may originate from many aspects such as the material itself, additives, production process or storage environment. Through professional odor analysis technology, such as gas chromatography-mass spectrometry (GC-MS), odor components can be accurately identified and provide a basis for subsequent solutions.

二、Choose low-odor materials

1. Environmentally friendly materials: Give priority to environmentally friendly, low-odor materials, such as bio-based plastics, PLA (polylactic acid) and other degradable materials. Not only do these materials have low odor, they are also environmentally friendly.

2. High-quality plastic: For plastic packaging materials, high-quality plastics with low odor and low residue should be selected, such as low-density polyethylene (LDPE), polypropylene (PP), etc. These materials release less odor during processing and have stable performance.

三、Optimize production process

1. Improve the printing process: If the printing ink on the packaging material is a source of odor, the printing process can be optimized and use low-odor, environmentally friendly inks and solvents. At the same time, the drying process after printing is strengthened to ensure that the ink is fully cured and reduces residual odor.

2. Control the production environment: Maintain good ventilation in the production workshop to reduce the accumulation of harmful gases. During the production process, parameters such as temperature and humidity are strictly controlled to prevent the material from producing odor due to environmental changes.

四、Strengthen storage management

1. Choose a suitable storage environment: Cosmetic packaging materials should be stored in a dry, ventilated, and light-proof environment to avoid adverse conditions such as high temperature and humidity that may cause the materials to age, deteriorate, and produce odor.

2. Regular inspection: Regularly inspect stored cosmetic packaging materials to detect and deal with odorous products in a timely manner to prevent them from entering the market.

五、Use odor absorbers

Add an appropriate amount of odor adsorbents, such as activated carbon, zeolite, etc., to cosmetic packaging materials. These materials have strong adsorption capabilities and can effectively remove odors in packaging materials. However, it should be noted that the selection and usage of adsorbents should be adjusted according to the actual situation to avoid affecting the cosmetics themselves.

As people's awareness of environmental protection increases, a packaging container called "ecological glass bottle" is also an important development direction of glass containers in the future. Cosmetic packaging manufacturers can also help remove odors by treating plastic particles with a special detergent solution. Generally these cleaners are water-based or alkaline solutions containing surfactants. These cleaners can effectively remove vinyl chloride monomer, styrene, acrylates, acrylic monomers and unsaturated hydrocarbons.
