Plastic Bag Sealing Machines

Sealing a plastic bag might become necessary when wrapping homemade presents or cooking in the sous vide style. With a special heat sealer, also known as direct heat sealer, hand sealer, heat impulse sealer and bag sealer, you can complete this task in no time. When choosing a plastic sealing machine for your needs, consider some basic points, such as type, size, speed and packaging material.

Plastic Bag Sealer Type

The heat sealers fall into two main categories based on the function. Impulse heat sealers are ready for use without any warm up time required and after applying a pulse of energy to the sealing area they also cool down quickly. The impulse sealers have several subtypes that are suitable for different materials. Direct heat sealers maintain constant heat in their jaws and use power as long as the machine is on. These are better for sealing thicker materials because their heat penetration is deeper. In addition to the two main sealer types there are some other specialised sealers like the vacuum sealer or the clamshell sealer.

Plastic Bag Sealer Size

The plastic bag sealer size depends on the size of the plastic bag you need to seal, namely, its width. As the cutters on the device typically trim at a point that is lesser than the sealer arm's width, add some centimetres to the sealer arm when choosing one.

Plastic Bag Sealer Speed

The speed of a sealing machine is measured by the number of units it can seal in a minute. High production jobs require fast sealers like the continuous band sealer or the automatic sealer. However, the faster models are also larger and better for industrial settings. For home use, choose a small portable sealer or a hand sealer that can seal about 6-15 packages per minute.

Packaging Materials for Sealing

The material of the packaging material to be sealed determines which kind of sealer you should choose. Impulse sealer is suitable for materials that require low sealing temperature. These include thermoplastic materials like polypropylene, polyurethane, nylon, bubble cushioning wraps, foil and polyethylene. Direct heat sealers can handle thicker materials, such as cellophane, waxed paper, poly cello film, coated aluminium foil and gusset bag.
