Flexographic printing sleeves

What are flexographic printing sleeves?

Flexographic printing sleeves are used to mount printing plates on it. Printing plates are mounted on the flexo plate sleeves, which are floated onto the air mandrel by using compressed air. Initially, flexographic printing plates were mounted on the cylinders directly. But since plates were not easily interchangeable and using multiple cylinders for several jobs lead to high costs and storage problems, flexo printing sleeves were developed. The main advantage of the flexo printing sleeves is that they can be easily floated on and off the air mandrels. The flexographic printing sleeves are also known as “Plate carriers”, “Plate sleeves” or “Press sleeves”.

What different type of print sleeves do we offer?

Why is tech sleeve different?

Tech Sleeves is a flexo sleeve manufacturer. At Tech sleeves®, we offer plate sleeves and bridges (adapters) for the global flexographic printing industry. We believe that we can increase the printing quality and overall efficiency through a combination of experience and innovation.

Features and benefits of a Tech Sleeve

The high-quality raw materials such as the composite combination of volumized fiberglass infused with vinyl-ester epoxy resin, provides flexural strength and form stability to the Tech Sleeves, reducing the bouncing caused by deflection during printing.

Sleeve Materials

Sleeve Materials

1

Base layer

The base layer features an expandable and an extremely durable base layer (1mm). This contains Dyneema that offers maximum strength with minimum weight. Dyneema has good abrasion resistance and is 40% stronger than aramid fibres with added benefits such as resistant to moisture, UV lights and chemicals.

2

Compressible Layer

The foam layer offers high rebound resilience and 50% compressibility without bulging. Because of this, it enables the sleeve to expand and have a perfect fit. Furthermore, the foam layer will not deform and has good abrasion resistance from ageing and weathering.

3

Tech Core Material Layer

The Tech Core layer contains Sphere Core SBC, which is pre-compressed, stitch-bonded core material based on fibreglass. It makes the sleeve pressure-resistant, water-resistant and provides excellent form stability. Because of this, the sleeve is customizable and can be produced with the required wall thickness.

4

Outer Surface Layer

The outer layer features Vinyl-Ester resin reinforced by a sandwich construction of fibreglass material. It has high chemical resistance, heat resistance and excellent tape adhesion.
