Glass

Permanent marking on glass is commonly realized via UV curing technology. Lanyin supplies a full portfolio of UV inkjet coding systems capable of stable high-speed operation to satisfy large-scale industrial production requirements. Whether you prefer labelling or direct inkjet marking on glass items, our comprehensive product lineup covers matched inks and labelling technologies available for selection and customized development upon request.

Solutions:

Our dedicated industrial inkjet coding solution is customized for glass manufacturing and deep-processing production lines. The coding unit can be fixed on glass tempering lines, bottle forming conveyors and finished glass packaging equipment to support high-speed inline continuous marking as well as offline static batch coding for small customized orders. It overcomes typical industry challenges including poor ink adhesion on smooth non-porous glass, code shedding after high-temperature annealing and frosting treatment, and ink bead shrinkage on glossy surfaces, achieving stable consistent coding from semi-finished glass blanks to finished glass products.

Application Markets:

The marking system serves comprehensive glass production sectors. Common applicable products include beverage glass bottles, cosmetic glass containers, pharmaceutical vials, tempered architectural glass, glass tubes, glass tableware, automotive glass and handmade craft glass. It covers food & drink bottling plants, pharmaceutical packaging factories, daily chemical container workshops, construction glass processing enterprises and automotive component manufacturers.

Printable Substrates:

Compatible with various glass substrates ranging from transparent soda-lime glass, borosilicate glass, frosted matte glass, coated painted glass to curved shaped glass and recycled processed glass. Specially tuned inks and printing parameters are optimized for dense, impermeable smooth glass characteristics to avoid ink beading, crawling or detachment without extra surface polishing or primer preprocessing.

Printing Content:

The equipment supports flexible printing of fixed and variable data on glass surfaces such as production batch numbers, manufacture dates, expiry codes, mould numbers, specification parameters and manufacturer identification codes. Besides standard texts and numerals, it prints high-precision 1D barcodes, traceable QR codes, anti-counterfeiting encrypted codes and customized brand logos. All variable data can be imported from external databases for real-time modification and batch variable-data printing.

Ink Features:

  • Strong Adhesion: Specially formulated glass ink forms tight bonding with slick glass surfaces and resists peeling after washing, high-temperature baking and long-term storage.
  • High Definition & Fine Printing: Produces crisp tiny characters and delicate patterns suitable for narrow-area marking on small glass vials and miniature containers.
  • Scratch & Wear Resistance: Printed imprints withstand repeated wiping, packaging friction and long-distance transportation abrasion while keeping full readability.
  • Temperature & Humidity Resistance: Marks remain intact after high-temperature annealing, cold storage and humid warehouse environments without fading or blurring.
  • Fast Drying Performance: Instant surface drying right after printing to avoid smudge during high-speed conveying and subsequent packaging procedures.
  • Diversified Ink Options: Available with black, white, pigmented color, food-safe and high-temperature resistant inks to match transparent, dark-tinted and colored glass differently.

Importance of Component Marking:

  • Product Specification Identification

    Glass items often share similar appearances with divergent specifications and production batches; printed model and batch information enables quick accurate sorting during incoming inspection and warehouse inventory management to prevent product mixing.

  • Guiding Customer Choice

    Clear surface markings display product credentials and production standards for distributors and end buyers to facilitate informed purchasing decisions.

  • Full Lifecycle Traceability

    Unique coded markings realize full-chain traceability covering glass raw material melting, deep processing, warehousing and terminal sales, supporting precise quality tracking and efficient product recall management.

  • Brand Reputation Protection

    Durable standardized marking restrains counterfeit inferior glass goods from market circulation and effectively safeguards enterprise brand image and commercial benefits.

  • Anti-Counterfeiting Security

    Custom encrypted QR codes and exclusive anti-fake imprints allow instant authenticity verification to protect both brand rights and end-consumer interests.

  • Market Expansion & Sales Growth

    Clean long-lasting marking works as intuitive quality certification, boosting buyer trust and purchase willingness to drive steady sales growth and market expansion.
