Overview

Molded Polyurethane for Food & Beverage Applications

Food & Beverage

FDA-Compliant Polyurethane for Critical Food & Beverage Processes

Meridian Laboratory’s ML6 polyurethane parts are commonly used across the food and beverage industry for applications in rotary filling and capping, pharmaceutical packaging, glass container handling, fish processing, lid liner production, and pet food packaging. These parts are made with FDA-compliant urethane, are resistant to wear, and stay stable in wet, humid, and harsh conditions without losing shape or delaminating. They grip firmly with high friction, but don’t mark or damage the products they come in contact with. Because they’re molded to exact tolerances and bonded firmly, ML6 parts protect sensitive materials and limit production delays.

Application & Uses

Common Applications & Uses for Molded Polyurethane in Food & Beverage

Rotary Fill and Capping Pharmaceutical Packaging Machines Glass Container Processing Fish Processing Equipment Lid Liner Production Pet Food Packaging

Strong Bond & Durability for Harsh Environments

ML6 polyurethane coated yoke rollers and covered bearings are used on rotary filling and capping equipment that operate on a track guide assembly.

The ML6 Advantage

ML6 polyurethane rollers and bearings maintain shape and stability in harsh, wet, and humid environments. Their strong bond strength provides excellent longevity and minimizes costly downtime in continuous production settings.

FDA-Compliant & Manufactured for Repeated Use

ML6 FDA-compliant polyurethane coated grippers are used on pharmaceutical packaging machines to install caps and apply labels onto containers.

The ML6 Advantage

Molded with FDA-compliant polyurethane, our grippers offer high durability, strong bond strength, and excellent friction for reliable gripping and tightening of containers through repeated use.

Exact Tolerances & Superior Bond Strength

ML6 coated bearings and polyurethane idler rollers are widely used for guiding glass containers during filling, capping, and packaging operations.

The ML6 Advantage

Molded to exact tolerances for repeatability, ML6 polyurethane features an extremely strong bond strength and protects fragile glass containers during processing.

Flexible & Made for Harsh Conditions

ML6 FDA-compliant polyurethane rollers and grippers are used in fish processing equipment for sorting and packaging operations.

The ML6 Advantage

FDA-compliant ML6 polyurethane withstands wet and harsh fish processing environments. Its flexible design feeds uneven product sizes without crushing, maintaining performance through extended and continuous use.

Non-Marking with High Friction & Low RUNOUT

ML6 polyurethane molded shafts are used to feed rolls of material used to produce lid liners for food containers such as condiment and peanut butter jars.

The ML6 Advantage

ML6 polyurethane provides high friction, which helps feed thin materials smoothly and reliably. Its low total indicated runout (TIR) ensures precise rotation and reduces the risk of product damage during processing.

Long-Term Stability & Durable Bonding

ML6 polyurethane zero-crush wheels and covered bearings are used in the manufacturing of bags used to contain various types of pet food and animal feeds.

The ML6 Advantage

ML6 polyurethane exhibits strong bond strength and maintains composure over time, resisting delamination and staying stable despite constant motion and contact.
