Can Coating

Can Coating

Cans and can coatings are vital to the world

The metal packages we use every day play an essential role to the world’s recycling system, economy and food sustainability. The internal coatings and external coatings applied to these packages protect consumers and preserve the quality and safety of our food, beverage and personal care products. 

Food and beverage cans preserve the taste and nutritional values of their filling for up to several years. As a consequence of such long storage times, the interactions between the packaging and the food need to be minimized. Cans are typically coated with an organic layer that protects the integrity of the can from effects of the food and prevents chemical reactions between the can’s metal and the food. To fulfill the technical and legal requirements, can coatings should withstand the production and sterilization processes, be universally applicable for all food and beverage types, prevent chemical migration into food in quantities that endanger human health, adhere to the can even after non-intentional deformation, resist aggressive food types and protect the metal of the cans and preserve the food and maintain its organoleptic properties over several years.

Metal food packaging includes a wide variety of products such as cans, closures, lids, tubes, and aerosol containers among others. Cans are by far the most widespread, being canned foods and beverages an important part of the global food. The canning of food and beverages is still an important process in food preservation since foods packed in metallic cans have a longer shelf life compared to food packed in other materials.

At NewLifeChem, we work every day to develop and deliver coatings that achieve these goals and do our part in protecting and beautifying the world.

Why the world depends on can & packaging coatings

  • Prevents corrosion and spoilage
  • Upholds regulations
  • Helps maintain quality, flavor and freshness of contents
  • External coatings offer branding and marketing solutions

NewLifeChem Can coatings

Many different can coatings are commercially available, but most of them are based on a limited number of chemicals functionalities. Coatings contain different additives, e.g. agents to increase surface slipping as well as abrasion and scratch resistance of can coatings, lubricants, anti-foaming agents, adhesives, scavengers for hydrochloric acids, and pigments.

NewLifeChem Can Coatings are applied to the inner and outer surfaces of steel cans and aluminum cans for the purpose of protecting the contents of various beverages, foods, medicines, etc., as well as the surface of cans from scratches. In particular, it is a high-performance product that fully considers the safety and health of contents and the protection of flavor at the product quality design stage, and we also have a lineup of environmentally friendly water-based paints and UV Cure Coatings. Various metals such as aluminum, steel, and copper are given functionality such as scratch resistance, workability, corrosion resistance, and insulation.

1) Bavarage

Exterior Coatings

We have a diverse lineup, including clear varnish with retort resistance, matte varnish that enhances design, and high hardness varnish specialized in wear resistance. We can also make proposals tailored to your usage conditions, such as products that use new resins to reduce misting during painting and improve transportability.

Interior Coatings

In addition to conventional epoxy products, we have established the quality of environmentally friendly paints. We can make proposals that meet customer needs, such as providing retort resistance similar to the outer surface, optimizing spray suitability by controlling fluidity, and customizing coating film hardness to provide high workability so that it can be applied to bottle cans.

2) Lid material

Exterior paint

Our coil paint for lids is a water-based based paint and can reduce VOC. By controlling the rheology of the paint, it is designed to be suitable for high-speed painting. It has excellent scratch resistance and high workability, and has a proven track record with a wide range of customers.

Internal paint

It has content resistance, adhesion to substrates, and processability, and can be used for a variety of purposes, including acidic drinks, retort drinks, and beer. In addition, we have a large number of resin types and paints that are able to propose coating film performance that meets customer needs.

3) Food

Exterior paint

It has content resistance, adhesion to substrates, and processability, and can be used for a variety of purposes, including acidic drinks, retort drinks, and beer. In addition, we have a large number of resin types and paints that are able to propose coating film performance that meets customer needs.

Interior paint

It has content resistance, adhesion to substrates, and processability, and can be used for a variety of purposes, including acidic drinks, retort drinks, and beer. In addition, we have a large number of resin types and paints that are able to propose coating film performance that meets customer needs.

4) cap/crown

NewLifeChem has been supplying the coatings for interior and exterior application to Crown caps, ROPP, Screw caps, Lug caps and other closures for customers. It enables high adhesion with PE and PP liner materials. In particular, it is possible to design a paint that has good opening torque after retorting.

5) General can

Exterior paint

We have a wide selection of resins such as polyester, acrylic, and epoxy ester that can be baked at low temperatures in consideration of environmental issues.

Interior paint

For general can applications, we have resin types tailored to the application, such as high processability, high gloss, and color coating.

6) Water-based Can Coatings

A waterbased coating is an environmentally friendly surface treatment that uses water as a solvent to disperse the resin used to make the coating or paint. Water comprises a minimum of 80% of the solvent used. Its aim is to make the coating or paint an easy-to-apply, eco-friendly product. Waterborne coatings are widely used due to their low VOC (volatile organic compounds) content. 

7) UV-Cure Can Coatings

Recently, we have commercialized UV paints and started developing LED paints, and are pursuing unprecedented decorations by combining them with metal decorating inks.​ Sizing, white base coat and clear varnish formulations combine high performance for use with UV-cured inks provides the complete package: economics, performance, compliance and most importantly, total customer satisfaction.
