Frequently Asked Questions
  • What is the difference between an adjustable and random case sealer?

    An adjustable 3M-Matic™ Case Sealer is manually adjusted for each different sized box for both height and width. It is 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 width and height of boxes.
  • When should I use a top and bottom belt taper?

    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 4 belt system securely drives the carton through the case sealer without skewing or tipping the box. 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 is taped which keeps your operations running smoothly.
  • When should I use a side belt machine?

    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 are 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.
  • When should I use a bottom belt machine?

    Bottom belt drive 3M-Matic™ Case Sealers (denoted by the number 2 in the model number) only have 2 belts; therefore, require a little more weight in the box to positively convey through the case sealer. Because there are only 2 belts, bottom belt machines cost less than others and can be a great place to start to improve your productivity.
  • Not all my box sizes will fit through a 3M-Matic™ Case Sealer. What are my options?

    Sometimes there are box sizes that are outside the typical operating range of a case sealer. These 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.
  • I need to reduce my labor costs. How can 3M help?

    The short answer is that it depends on how you are 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 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 Specialists can best recommend a solution after visiting your location.
  • How long does a 3M-Matic™ Case Sealer last?

    3M-Matic™ Case Sealers have a great reputation in the market for being long lasting and durable. 3M has been selling 3M-Matic™ Case Sealers for 45 years and while all of these aren’t currently in operation, we have customers that are using equipment that is over 20 years old! Obviously operating conditions and maintenance impact that longevity and every customer’s factory is different. Nonetheless we are with you through the long term and we stake our reputation on it. This is long term investment.
  • What maintenance is required?

    Each operating manual details available parts and recommended maintenance procedures. Most 3M-Matic™ Case Sealer 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. Participation in the 3M Systems Agreement Program by purchasing Scotch® Box Sealing Tape makes these parts available at no cost to you. Otherwise there are a variety of ways to purchase 3M replacement parts.
  • What brand of tape do you recommend?

    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, the best carton sealing tape. You get great wet out of the tape on the box along with reliable and consistent performance.
