Case Sealers: 6 Factors to Consider When Choosing Equipment

How many cases a day does your crew have to seal? If it’s around 150 or more, then you should consider purchasing a case sealer.

This semi-automatic or fully automatic equipment is used to close and protect cases using adhesive tape.

Why use a case sealer? Because it offers numerous advantages:

  • You save by using less adhesive tape.
  • You reduce the number and frequency of injuries caused by performance of repetitive movements and the associated stress.
  • You increase your crew’s productivity.
  • You also ensure more efficient use of the tape, which is consistently applied in the right place at the right pressure.

Buying an industrial sealer can make a significant difference in terms of your team’s efficiency and output. What’s important is to select the right sealer for your needs.

6 factors to consider before buying a case sealer

It’s easy to get overwhelmed by the range of case sealers available on the market. To help make things clearer for you, we’ve made a list of the six key factors to consider in making your choice. They are:

1. Case size

Do an inventory of all case sizes you use, from smallest to largest. Check whether the sealer you’re interested in buying is compatible with all these sizes.
Important! Capacity can vary widely from one model to the next, even within the same line of sealers.

2. Case weight

Regardless of make, all sealers have a maximum capacity in terms of the case weight they can handle. For example, the Robotape units from Robopac have a capacity of up to 110 lbs., one of the highest on the market. When choosing a unit, consider the weight of your products and the requirements of your industry.

3. THE VARIETY OF CASES

Your needs will vary depending on whether the cases you seal are always the same size or of different sizes. If cases of different sizes will be passing randomly through the same production line, then the equipment has to be able to adjust automatically (otherwise, the operator has to adjust the settings before every box).

Not all sealers have the capacity to adjust automatically. Those offering this feature use sensors to adapt to the case size. Random, or auto-adjusting, case sealers are the best to use on cases of different sizes because they don’t require manual adjustment of the tape heads before every case.

On the other hand, if your case size is uniform, then a standard sealer model is perfect for you.

4. Work environment

Where do you plan to operate your case sealer? In a high-humidity environment or a normal working environment?

If the equipment will be used in a high-humidity or food production environment, then a stainless steel case sealer is preferable as it is better designed for these conditions.

If the sealer will be used in a normal working environment, then an enamelled steel model will be perfectly adequate.

It’s also important to consider how much space you have available for the equipment. Case sealers come in different sizes. Check first and avoid surprises!

5. Production volume

To make the purchase of a case sealer worthwhile, the volume of cases to be sealed should be around 150 or more cases per day. Once you have determined that this purchase is right for your business, take time to identify the model best suited to your anticipated production volume. Then, check the maximum output rate of the equipment you are considering to ensure that it will also be able to accommodate your future requirements.

6. Labour

When you picture integrating a case sealer into your production line, what do you have in mind? What are your goals? Do you want an operator to play a role in the sealing process, or do you prefer to run a fully automated process on a production line equipped with conveyors?

In the context of the current labour shortage, it’s important to assess your capacity to find workers today and down the road. If you’re having challenges finding skilled workers, then doesn’t this make automation an effective alternative?

Keep in mind also that your current reality could change.
