Water-Based Printing Inks & Varnishes for Packaging Printers

JLJ Coating is a Shantou-based supplier that provides water-based printing inks, varnishes, and adhesives specifically for packaging printers. The company matches products to specific substrates and processes, offering flexo inks for paper and gravure inks for treated plastic films. Their workflow begins with substrate identification, followed by process selection, color definition, and confirmation through press trials.

The business operates out of Shantou, China, and serves industries including food production, chemicals, and printing. They provide press trial support, press-side troubleshooting, and material sample services to help customers solve specific printing issues. Varnish and adhesive matching is offered based on verified substrate structures and target results.

Customers can start by selecting a product family, such as water-based flexo ink or gravure ink, then confirming the exact matching direction with substrate, press process, and trial requirements. The inquiry process involves identifying the substrate, selecting the process (flexo, gravure, or coating), defining color and finish targets, and confirming through press trials.

The company offers a range of specific products including water-based overprint varnish for inline gloss finishing, A0126 matte print-receptive varnish, soft-touch varnish, laminating adhesive for metallized PET film, and JD series transfer adhesive for paper.

To get started, clients are encouraged to send a clear WhatsApp message containing details about the printing process, substrate, product need, target effect, current issue, and estimated quantity. The company uses WhatsApp as its primary communication channel for inquiries and technical support.

The company provides press-side troubleshooting support for issues such as low drying, foaming, poor adhesion, weak rub resistance, and blocking. They also offer material sample services to help verify performance before full-scale adoption.

The company offers water-based gravure ink specifically for treated-plastic-film gravure trials where print structure, transfer, drying, and adhesion need review. This includes application-specific matching for selected plastic films like BOPP and PET.

For paper and paperboard packaging, the company supplies water-based flexo ink suitable for kraft paper, white card, coated paper, corrugated board, and paper bags. This covers a wide range of related paper-packaging jobs using a flexographic press.

The A0126 Water-Based Matte Print-Receptive Varnish is designed for a uniform matte surface intended for subsequent printing on paper, treated film, pearlized film, or verified synthetic materials. This product requires sample validation to confirm performance.

The L-2455 Water-Based Laminating Adhesive is specifically formulated for wet lamination trials using metallized PET film with paper or paperboard. This product targets specific structural applications in packaging.

The JD Series Water-Based Transfer Adhesive is intended for qualified paper transfer lamination or peel-transfer trials using verified PET or metallized transfer film. This supports specific transfer printing needs.

The company communicates primarily in English and Japanese, as indicated by the language options available on their website. They also offer WhatsApp support which allows for direct communication regardless of formal language barriers.

The company emphasizes a substrate-first matching approach, starting with substrate identification before selecting the process, defining color and finish targets, and confirming through press trials. This method ensures that the product matches the specific requirements of the packaging job.
