  • An adjustable 3M-Matic™ Case Sealer is manually adjusted for each different-sized box for both height and width. It's designed for long runs of same-sized cartons. With a random case sealer, the machine does the work. The 3M-Matic™ Random Case Sealer will automatically adjust for different widths and heights of boxes.
  • Top and bottom belt 3M-Matic™ Case Sealers (denoted by the number 7 in the model number) can be used in most carton-sealing applications. In fact, they are often the best drive system configuration and are highly recommended. The four-belt system securely drives the carton through the case sealer without skewing or tipping it. With the carton squarely held in place, the tape is securely applied down the center seam. Imagine a tall but not very long carton. With a top and bottom belt drive 3M-Matic™ Case Sealer, the carton doesn’t tip as it's taped, keeping your operations running smoothly.
  • Side belt drive systems—such as the 3M-Matic™ Case Sealers denoted by the number 8 in the model number—are especially useful for taping narrow-width boxes, although they're used for boxes of all sizes. Make certain the side belts are spring-loaded to allow a little give when box widths vary, such as with overstuffed cartons.
  • Bottom belt drive 3M-Matic™ Case Sealers (denoted by the number 2 in the model number) only have two belts, requiring a little more weight in the box to positively convey it through the case sealer. Because there are only two belts, bottom belt machines cost less than others and can be a great place to start improving your productivity.
  • Sometimes there are box sizes that are outside the typical operating range of a case sealer. They may be too short or too large. 3M-Matic™ Case Sealers can be customized to your unique box requirements. In some instances, it may be a simple extension of the columns. In others, we will engineer a custom sealer from the ground up using standard 3M-Matic™ Case Sealer components.
  • The short answer is that it depends on how you're packaging your product today. 3M-Matic™ Case Sealers can tape boxes for shipment and replace hand taping. Shifting to a flap-folding machine removes the need for an operator to fold the top flaps and present the box to the case sealer. A case sealer can be used to pre-form cartons, which can reduce your costs and increase productivity. A 3M Packaging Specialist can best recommend a solution after visiting your location.
  • 3M-Matic™ Case Sealers have a great reputation in the market for being long-lasting and durable. We've been selling 3M-Matic™ Case Sealers for 45 years, and while not every unit is currently in operation, we have customers who are using equipment that's over 20 years old. Obviously operating conditions and maintenance impact that longevity, and every customer’s factory is different. Nevertheless, we are with you through the long term, and we stake our reputation on it. A 3M-Matic™ Case Sealer is a long-term investment.
  • Each operating manual details available parts and recommended maintenance procedures. Most 3M-Matic™ Case Sealers are basic machines, and there are a few wear parts that need periodic replacement depending on usage. These include drive belts and taping head blades to cut the tape. Participating in the 3M Systems Agreement Program by purchasing Scotch® Box Sealing Tape makes these parts available to you at no cost. Otherwise, there are a variety of ways to purchase 3M replacement parts.
  • Scotch® Box Sealing Tape is our strong recommendation. 3M-Matic™ Case Sealers and Scotch® Box Sealing Tape are engineered to work together as a system, providing you the best equipment, the best taping head and the best carton-sealing tape. You get great adhesion, along with reliable and consistent case sealer performance.
