In the packaging industry, the effectiveness of adhesive, printing, spraying and other processes directly depends on the pre-treatment quality of the material surface. Can AF plasma spraying coating equipment be applied in the field of packaging printing? Today, the editor will lead everyone to learn about the charm of AF plasma spraying coating equipment in the field of packaging printing!

Firstly, in the field of packaging and printing, such as toothpaste boxes, cosmetics boxes, cigarette boxes, wine boxes, electronic toys or product boxes, it is common to encounter the problem of glue opening in packaging boxes. For example, in terms of gluing boxes, plasma cleaning technology is used to first treat the surface of the packaging material. Plasma (such as argon gas, oxygen) is used to bombard the material surface, achieving micro etching and activation, improving surface energy and dyne value, laying the foundation for AF coating adhesion, improving its surface performance, and enhancing the adhesion between glue and material, saving glue costs.

Secondly, in terms of printing: AF plasma spray coating equipment can improve the wettability and roughness of packaging material surfaces, allowing ink to spread and adhere better on the material surface, thereby improving printing quality and reducing issues such as ink detachment and inaccurate overprinting during the printing process. For example, in the pre-treatment of printing materials such as plastic film and cardboard, plasma technology can significantly improve the adhesion of ink.

Again, AF plasma spraying equipment can remove dust, oil stains, paper powder and other impurities on the surface of packaging materials without leaving any traces on the treated surface, and also reduce the generation of bubbles. This is crucial for ensuring the quality of subsequent adhesive, printing, spraying and other processes, avoiding problems such as poor adhesion and unclear printing patterns caused by surface contamination.

For some difficult to stick or non-polar materials, such as polypropylene, polyethylene, and recycled materials, AF plasma spraying equipment can change the chemical properties of the material surface through the action of plasma, activate its surface, and improve the compatibility and bonding strength between the material and adhesives, inks, coatings, etc.

AF coating spraying equipment can use plasma assisted spraying technology to atomize fluorinated siloxane or nano ceramic materials into nano-sized particles, which are uniformly deposited on the surface of the substrate to form functional thin films with a thickness of only 0.1-5 μ m.

As is well known, the core properties of AF coatings are as follows:

1. Can reduce fingerprint residue: By using low surface energy (contact angle ≥ 110 °), hydrophobic and oleophobic properties can be achieved, making it difficult for fingerprints, sweat, and other stains to adhere. Even if there is residue, it is easy to wipe off. AF plasma spraying coating equipment can form a very thin nano scale fingerprint film on the surface of packaging and printing fields. This film has extremely low surface energy and can effectively prevent the attachment of fingerprints, oil stains, dust, and other stains, significantly reducing the difficulty of cleaning and maintaining the appearance and cleanliness of the shell.

2. Improving wear and scratch resistance: The nanoscale dense structure can enhance surface hardness (2-4H), avoiding scratches caused by friction during transportation, thereby extending the product's service life.

3. Enhanced optical transparency: The coating transmittance is greater than 95%, which does not affect the color reproduction and texture of packaging printing patterns (such as high gloss packaging boxes, transparent window films).

4. Durability and chemical stability: AF coating technology has characteristics such as wear resistance, high temperature resistance, and chemical corrosion resistance, which can maintain its performance under various environmental conditions and protect the packaging printing field for a long time.

In summary, today the editor has introduced the application of AF plasma spray coating technology in the packaging and printing industry and plastic parts. If you have any questions, please feel free to chat with our vibration instrument colleagues privately!
