Blocking Tester for Plastic Film Using the Parallel Plate Method
A precise instrument specifically built to measure the unwanted sticking between layers of plastic sheet materials.

This Blocking Reblock Tester, built with a specific purpose in mind, works to find and identify that sticky grip that you do not want occurring between sheets stacked on top of each other. By using a small and space-saving mechanical system for balancing, the BRB adds weight little by little, matching the pace of 90 milliliters of water every minute.
Regardless of what you are manufacturing, if your product involves layers of material touching each other, the Blocking Tester for Plastic Film offers the reliability you need. Here is where you will see this instrument making a difference:
- Makers of Flexible Wrappers and Food Containers
Companies that create soft coverings for snacks, fresh produce, and baked goods rely on the Blocking Reblock Tester to guarantee that their packaging materials do not cling tightly together, ensuring that bags open easily for the person buying the groceries. - Creators of Large Farming Sheets and Greenhouse Covers
Producers of heavy-duty outdoor plastics depend on the Parallel Plate Blocking Tester to check and see if their protective rolls used in agriculture can be unrolled without tearing after sitting in hot storage warehouses for long periods of time. - Factories Producing Garbage Liners and Carrier Sacks
Manufacturing plants that turn out thousands of trash bags and shopping totes implement the Blocking Reblock Tester to confirm that the openings do not fuse into a solid block of plastic, making sure customers can grab just one sack at a time without frustration. - Developers of Chemical Mixtures and Additives
Lab teams working on special powder formulas employ the BRB instrument to figure out if their new recipes for preventing stickiness (anti-blocking agents) are actually working to keep plastic surfaces slippery and separate from each other. - Suppliers of Medical Pouches and Sterile Barriers
Businesses that build sterile packets for doctor’s tools and medicine need the Blocking Tester for Plastic Film to make certain that the protective layers peel apart smoothly so that critical health supplies are quick to access during urgent hospital situations. - Print Shops and Material Processors
Facilities that run high-speed machinery to add ink or coatings to film count on the Parallel Plate Method to avoid jamming their production lines, ensuring that rolls of material feed through without getting stuck or snagged on the metal rollers and guides.
