Application In Aluminum Can Industry

▎Product Overview

Formed from a single piece of metal (usually aluminum or tinplate) using a deep drawing process to create the body and bottom as one piece, then adding the end. Printing is done before forming.

Optimized for Pre-Forming Printing
Specifically designed for printing on flat aluminum or tinplate sheets before the deep drawing process forms the can body and bottom as one integrated piece.

High-Strength Metal Reinforcement
Multi-layer construction ensures excellent dimensional stability, preventing stretching or distortion during high-speed metal decorating.

Precision Compressible Layer
Engineered compressible layer provides uniform pressure distribution, ensuring consistent ink transfer prior to forming and maintaining image integrity after deep drawing.

Abrasion-Resistant Surface Compound
Durable elastomer surface withstands continuous contact with metal sheets, reducing wear and extending service life in demanding can-printing environments.

▎Printing Characteristics

Printing is performed on cup-shaped or shallow-dish-shaped metal blanks(which are later deep-drawn into the can body).

The substrate surface is not perfectly flat and has curvature.

Printed coatings and inks must withstand subsequent severe stretching (deep drawing). This demands very high stretchability, flexibility, and adhesion from inks and coatings.

Higher demands on blanket elasticity, compressibility, and uniform ink transfer to adapt to the curved surface and subsequent deformation.

Unlike flat-sheet printing, this process requires the blanket to conform precisely to pre-formed metal surfaces with varying depths and contours. The blanket must deliver uniform contact across the entire printable area, including edges and transitional curves, without creating pressure concentration or image distortion.

Because the substrate surface is not perfectly flat and exhibits noticeable curvature, the rubber blanket must provide exceptional conformability and surface contact performance. The curved geometry of cup-shaped blanks introduces uneven pressure distribution during printing, which can easily lead to incomplete ink transfer, ghosting, or localized wear if the blanket lacks sufficient flexibility.

Excessive ink buildup can crack or delaminate during forming, while insufficient ink coverage may reduce color intensity or protection performance. H&Z rubber blanket precisely engineered surface ensures uniform ink film thickness, which is critical to maintaining coating integrity after stretching.

Since the printed substrate will undergo substantial deformation after printing, the blanket must first ensure that the applied image can tolerate such transformation without visual or structural defects.

This combination of elasticity, structural stability, and controlled ink transfer ensures H&Z rubber blankets with reliable decoration quality, extended service life, ultimately improving overall productivity in 2-piece can manufacturing.

▎Recommended Blanket Types

Medium Blankets:

The workhorse for two-piece can printing.

Advantages: Compared to hard blankets, they offer better elasticity, compressibility, and cushioning. This helps ensure uniform, stable ink transfer onto the slightly curved blank surface during printing, reducing defects like ghosting/scuffing caused by uneven pressure. Their moderate hardness still meets general accuracy requirements.

Use Cases: Printing for the vast majority of two-piece cans (aluminum cans, steel two-piece cans).

Soft Blankets:

Used in specific situations.

Advantages: Best elasticity and cushioning, maximum adaptability to complex or irregular surfaces, provides the most uniform pressure and ink transfer.

Disadvantages: May exhibit slightly higher dot gain than medium or hard blankets. Registration accuracy might be slightly lower (though this gap is narrowing with material advancements).
Use Cases: Two-piece can printing where extreme curved surface adaptability is required, substrate thickness or flatness varies slightly, or specific ink transfer characteristics are needed.

▎Selection Advice

Identify Can Type

First, determine if printing for two-piece or three-piece cans.The first and most critical step in selecting the correct rubber blanket is to determine whether the printing application is for a two-piece can or a three-piece can. This is because the manufacturing structure and printing process of these two can types are fundamentally different, directly influencing blanket performance requirements.

Consider Primary Needs

Three-Piece
Focus on registration accuracy, dot reproduction → Prioritize Hard.
Three-piece cans are made from a rectangular metal sheet rolled into a cylindrical body and welded along a side seam, with separate top and bottom ends attached later. Printing is usually done on flat sheets that do not undergo severe stretching afterward. As a result, the blanket requirements focus more on surface durability and registration accuracy rather than stretch accommodation.

Two-Piece
Focus on curved surface adaptability, uniform ink transfer for deep drawing → Prioritize Medium.
In contrast, for two-piece can production, the body and bottom are formed from a single metal sheet through a deep drawing and ironing process. Printing is typically performed on flat sheets or pre-formed cup-shaped blanks before final forming. The printed image must withstand significant stretching and deformation during deep drawing.
Therefore, the rubber blanket must provide exceptional elasticity, precise compressibility, and uniform ink transfer to ensure the printed layer maintains adhesion and integrity after forming.

▎Application In Aluminum Can Industry

Coca-Cola

H&Z rubber blankets play a critical role in the production of aluminum beverage cans for globally recognized brands such as Coca-Cola. Our rubber blankets help beverage manufacturers maintain strict global branding standards while maximizing productivity and minimizing downtime.

Sprite

In the production of aluminum cans for Sprite, H&Z rubber blankets for 2-pcs can ensure smooth, even lay down of both solid colors and halftone areas, maintaining strong ink adhesion to the aluminum substrate.

Moreover, Sprite cans are produced at high speeds in large volumes, requiring blankets with excellent fatigue resistance and long service life. Stable compressibility and fast elastic recovery guarantee reliable performance throughout extended production cycles.

Beer

Rubber packaging market are also widely used in the printing of aluminum beer cans, where many beer brands utilize intricate graphics, textured finishes, multi-color layers, and specialty coatings to stand out on retail shelves. These designs remain intact after the deep drawing process used in H&Z two-piece can manufacturing.

▎Win-Win Choice

Beyond supplying materials, H&Z supports custom manufacturing for two-piece can rubber blanket, adapting structural designs and printing effects, matching all of clients branding and functional demands.

From concept development to finished packaging, we coordinate every stage to ensure consistent quality, durability, and visual excellence. By integrating materials, consumables, and technical expertise, H&Z enables customers to enhance brand presence, improve operational efficiency, and achieve superior market performance through truly customized solutions.
