Pressure-sensitive adhesive (PSA) materials create unique challenges for converting operations. In label manufacturing, printing, and other web-processing applications, adhesive-backed materials generate trim and matrix waste that must be removed continuously to keep production moving. But when sticky scrap enters a pneumatic conveying system, it can adhere to duct walls, accumulate over time, and eventually cause costly blockages.
The solution starts with understanding the material and choosing the right waste-handling equipment. With properly configured trim cutters and an effective conveying system, manufacturers can reduce interruptions, improve waste removal, and maintain production efficiency.
Why PSA Trim and Matrix Waste Cause Clogs
PSA materials are designed to stick, which makes them particularly difficult to manage once they become production waste. During label converting, for example, matrix waste is the leftover material surrounding die-cut labels. Edge trim is generated when manufacturers cut material to the desired width.
When these materials enter ductwork, exposed adhesive can cause individual pieces to cling to internal surfaces. As additional waste passes through the system, it may accumulate around these initial attachment points, gradually restricting airflow and eventually obstructing the duct.
The consequences extend beyond a clogged pipe. Production teams may need to stop equipment, clear blockages, and perform additional maintenance. Inconsistent waste removal can also contribute to web breaks and limit the speed at which converting lines operate.
Manufacturers should address adhesive behavior as part of the overall system design rather than treating recurring clogs as isolated maintenance issues.
Choose Trim Cutters Designed for Your Material
BloApCo offers trim cutters designed for a range of converting applications, including pressure-sensitive label stock and adhesive matrix waste. Selecting equipment appropriate for the material supports consistent waste removal while minimizing unnecessary production interruptions.

One of the most effective ways to improve trim removal is to cut continuous scrap into smaller, manageable pieces before conveying it to a collection point.
Without cutting, long strips of trim can twist together, form tangled masses, and obstruct ductwork. Properly selected trim cutters reduce this risk by processing continuous material into pieces that are easier to transport through a pneumatic conveying system.
However, not every application presents the same challenge. Material thickness, adhesive properties, web speed, trim width, and the number of pickup points all influence equipment selection.
Address Adhesive Buildup Inside the Conveying System
Cutting sticky waste into smaller pieces is important, but it may not eliminate every adhesive-related challenge. PSA scraps can still adhere to equipment surfaces and ductwork, particularly when the material and operating conditions are not properly matched to the system.
For demanding applications, additional components may help reduce buildup. Depending on the material and system configuration, an oil-mist unit can introduce a controlled lubricant into the conveying process to help manage adhesive accumulation.
BloApCo identifies oil-mist units among the ancillary equipment that may be incorporated into matrix and trim removal systems for adhesive applications. The appropriate configuration depends on the specific waste stream and operating requirements.
Manufacturers should also evaluate airflow, duct routing, and collection arrangements as part of a complete system assessment. A solution that works well for one material or production line may not deliver the same results under different conditions.
The objective is to design a system that handles the scrap reliably from the point of generation through final collection, rather than relying on repeated cleanouts to maintain production.
Consider a Bagclone Stand-Alone System
Not every facility needs a large, centralized waste-handling installation. For operations looking to improve matrix removal at an individual production point, a Bagclone Stand-Alone System may offer a practical alternative.
BloApCo’s Bagclone is designed as an entry-level solution for managing trim and matrix waste. It combines the essential components of a waste-removal system in a stand-alone configuration, making it an option for facilities seeking a straightforward installation without the scope of a larger, multi-line system.
By cutting matrix waste into smaller pieces and continuously removing it from the production process, the system can reduce reliance on traditional rewinders. This can minimize interruptions associated with removing accumulated waste rolls and help keep production moving.
For converters experiencing frequent matrix removal issues, evaluating a stand-alone solution may be a useful first step toward more consistent waste handling.

Take a Proactive Approach to Waste Handling
Preventing ductwork clogs requires more than responding when airflow drops or production stops. A proactive approach considers the entire waste-removal process, from material generation to collection.
Start by identifying where blockages occur most frequently and which materials are involved. Review whether the existing cutter is suited to the scrap’s thickness and adhesive characteristics. Then, assess whether additional components or a different system configuration could improve performance.
Routine inspections and equipment maintenance also remain important. Knife condition and system airflow can affect waste-handling performance. Monitoring these factors helps teams identify developing problems before they cause significant downtime.
BloApCo’s technical literature library provides additional product information and application resources to help manufacturers evaluate their equipment needs.
Keep Sticky Waste From Sticking Around
Recurring ductwork clogs do not have to be an unavoidable part of production. By selecting appropriate trim cutters, addressing adhesive buildup, and choosing a waste-removal configuration that fits the application, manufacturers can work toward more reliable conveying and fewer production interruptions.
Whether you need a targeted solution for one converting line or a system designed for a broader operation, BloApCo can help you evaluate your trim and matrix removal requirements.
