What are the surface treatment methods for acrylic cream jar

The surface treatment of acrylic cream jars is an important part of ensuring their adhesion and wear resistance. Due to the smooth surface properties of acrylic materials, it is difficult to achieve a firm bonding of materials such as coatings or labels, it is particularly important to use appropriate surface treatment techniques to improve their surface roughness and polarity. The following are several common surface treatment methods and their advantages and disadvantages.

Solvent cleaning is a technology to remove contaminants such as grease, dust and other surfaces of acrylic cream cans through a specific solvent. This method can effectively improve the wettability and adhesion of the surface, and is easy to operate and inexpensive. However, caution is required when selecting solvents. Excessive or improper use of solvents may cause damage to the acrylic material, thereby affecting its performance.

The surfactant treatment method is to form a thin film on the surface of the acrylic cream pot, changing the polarity of the surface to enhance adhesion. This method is suitable for products with high requirements for surface adhesion. However, the selection and concentration of surfactant needs to be carefully controlled to avoid the impact on subsequent coatings or labels.

Flame treatment method uses high-temperature flame to quickly heat the surface of the acrylic cream pot, causing an oxidation reaction on the surface to generate polar functional groups, thereby significantly enhancing adhesion. This method has the advantages of fast processing speed and obvious effect, but during operation, the temperature and heating time of the flame need to be strictly controlled to prevent thermal damage to the acrylic material.

Ultraviolet (UV) treatment method irradiates the surface of the acrylic cream pot through ultraviolet rays, causing it to undergo a photochemical reaction to form polar functional groups to enhance adhesion. This method is environmentally friendly and pollution-free, but requires professional UV equipment support and has a relatively long processing time, making it suitable for production occasions with high environmental requirements.

The plasma treatment method is to bombard the surface of the acrylic cream pot by plasma discharge, causing chemical reactions and physical etching to significantly increase the roughness and polarity of the surface. This method has excellent processing effect and is suitable for products with extremely high requirements for surface quality, but its equipment costs are high and requires professional skills in operation.
