System and Method for Bag Closure Clip Production Making the Little Clips That Seal Your Bread Bag, Faster and Cleaner

This patent describes a system and method for producing bag closure clips, the small flat clips used to seal bread, produce and other bags. It covers how the clips are manufactured from sheet stock so they can be made efficiently and consistently at scale.

The Problem

The humble bread clip is produced in enormous quantities, which means even tiny inefficiencies in manufacturing add up. Clips must be formed to precise dimensions so they grip a bag’s neck reliably, release cleanly from the production tooling, and can be printed or shaped for branding. Traditional production has to balance speed, material use and accuracy, and any wasted material or jammed tooling on a high-volume line is costly. Improving how clips are cut and formed from the source material is therefore worth real money across millions of units.

What This Invention Does

The patent provides a system and method for bag closure clip production that defines how clips are formed from a sheet or web of material, covering the cutting and forming steps and the equipment that carries them out. By specifying the production approach, the invention aims to make clip manufacture faster, more material-efficient and more consistent, while supporting features such as custom shapes or printing. In practice this means a more streamlined route from raw sheet stock to finished closure clips ready for use on packaging lines.

Key Features

• Sheet-to-clip production. Clips are formed from sheet or web material through defined cutting and forming steps.
• High-volume focus. The method targets the efficient, repeatable output needed for a very high-volume product.
• Consistent dimensions. The approach supports clips formed to reliable, precise dimensions.
• Material efficiency. Streamlined forming helps reduce waste across large production runs.
• System and method. The claims cover both the production equipment and the manufacturing process.

Who Is Behind It

The applicant is Bedford Industries, Inc., a United States company known for twist ties, bag closures and related packaging products. The named inventors are Mark Green, Trevor Wintz and Isaac Christopher Steele. The application is a divisional that entered the national phase from an international filing.

Why It Matters

Closure clips are a small but ubiquitous part of food and produce packaging, and the economics of making them depend on squeezing out waste and downtime. A more efficient production system supports both cost and sustainability goals, since less wasted material means a lighter footprint per clip. Protecting the method in Australia supports Bedford’s supply and licensing interests in the local packaging market.
