TROUBLESHOOTING – Impulse Sealers

We created this troubleshooting guide to help with our most frequently asked questions regarding sealers.

Impulse sealers (hand, foot, automatic) work in a similar manner – often, if you are having a problem with your sealer, the solution can be found in the following parts:  heating element, PTFE adhesive, PTFE cover, microswitch, mounting spring, and/or timer.  Let us know if you have a problem that isn’t listed in this guide and we can try and assist you.

  1. Check element and PTFE cover and adhesive.
    • Element: This is the wire (flat or round) that heats up to seal or cut the bag/film. Remove the PTFE cover and check that the wire is not discolored, bent, or broken.
    • PTFE Adhesive: This is the 1/2″ piece with an adhesive backing UNDER the heating element.  It should extend past the seal area 1/2″ on either side because it is the barrier between the metal machine and the metal heating element. For the PTFE adhesive, you must replace the bottom sealing strip whenever you change the element.  The adhesive serves as a barrier between the heating element and the sealer’s body.  When the sealer’s heating element has burned through the bottom adhesive and arc’ed on the sealer’s body, the element will break as well as destroy the timer.
    • PTFE Cover: The PTFE cover that goes over the heating element must be whole to prevent the plastic bags or film from sticking to the element. For the teflon cover, we recommend changing the cover BEFORE it burns through.  As the cover wears, you will see a discoloration where it comes into contact with the element, you may also notice that your element is sticking to the thermoplastic material you are sealing.  You can maneuver the cover back and forth to allow the element to come into contact with the unused portions of the PTFE cover. If you are sealing/cutting a thicker plastic material (higher amount of heat) you may go through a lot of PTFE covers.
  2. Listen for “click” from microswitch when pushing bar down. This click should occur right before the upper bar comes into contact with the lower. If there is no click try the following:
    • Hand Sealer: Slightly bend metal switch lever so that when arm of sealer is brought down, the lever makes contact with microswitch and a click can be heard.
    • Foot Sealer: Small bolt for limit switch must be tightened as needed to make contact with the microswitch.
    • Auto Sealers: A 3.5″ screw that is mounted on upper jaw must be loosened so that it will make contact with microswitch which is mounted on left side of hinge bracket.
  3. Mounting Spring: Make sure that the spring the element mounts on is intact. Replace if damaged.  Please check also that the mounting spring is not rusted or worn in any way as this will prevent the element from conducting heat.
  4. Timer Light: The light on the timer should come on briefly when the seal bar is brought down for sealing. If it does not come on, the timer PC board probably needs replacing.

Impulse Sealers – How to Achieve the Best Seal

Good seals require not only enough heat to melt a bag together, but also enough cooling time to allow the seal to set.  Our most common complaint is that a sealer is not creating a good seal and 99% of the time, the operator is not holding the arm down long enough to allow the seal to cool and set.   Manual impulse sealers such as your hand or foot sealer require a congeal or dwell step to create a proper seal on your bag or film.   To achieve the best seal, hold the arm or upper jaw of your sealer down for an additional 2-4 seconds after the signal light has turned off to allow the seal to cool and set.

Follow our simple instructions below and you will get great looking seals!
1)   Set the timer at 3 and place your bag on the seal surface.
2)  Bring the upper jaw and seal arm down on the bag and hold in place until the  timer light goes out and continue to hold the upper jaw or seal arm down for an additional 2-4 seconds to set or congeal the seal.
3)  Lift the upper jaw or seal arm; test the bag or film.  If the seal is strong, the timer setting is correct.  Increase or decrease the timer setting slightly and test again until you achieve the perfect seal.

**Higher timer settings and thicker materials require longer congeal times.
**Following the above instructions will lengthen the life of all the parts.

How to Choose a Heat Sealer

When selecting a sealer, it is important to have a sense of the material which will be sealed.  Try and have the material thickness and width available as this will make your selection process much easier.  This will ensure the sealer you purchase is capable of sealing your material.  If you want any sealer suggestions, fill out this easy questionnaire and we will provide you with some suggestions

This page discusses the four key characteristics of sealers to help you determine which best fits your application.
What is a heat sealer?
A heat sealer (ex: bag sealer, heat impulse sealer, direct heat sealer, hand sealers) is a machine used to seal plastic material using heat. There are many types of sealers and choosing the right sealer may be overwhelming without a few basic points.
Function

There are two main types of sealers: (1) impulse heat and (2) direct heat.

Impulse sealers require no warm up time and seal by applying a pulse of energy to the sealing area, followed immediately by cooling.  Impulse sealers only use power when the jaw is lowered.  We recommend an impulse sealer for any thermoplastic material such as polyethylene (PE) or polypropylene (PP) which requires a lower seal temperature.  Materials for impulse sealers:  Polyethylene, Polyurethane, Polyvinylchloride, Pilofilm, Polyvinyl Alcohol, Saran, Nylon, bubble packs, padded mailers, foil, coated bags, Kel-F, Polyflex, Mylar, Tyvek, and other thermoplastic material.  Impulse sealers are easy to use (no warm-up time), economical (electricity used only during sealing process), and safe (no component is always hot).

There are different types of impulse sealers based on type of material and usage:

  • Hand sealers can seal poly material up to 10mil thickness
  • Pedestal Type / Foot sealers can seal poly material up to 15mil in thickness
  • Auto sealers can seal poly material up to 15mil in thickness
  • Double impulse sealers (automatic and foot options) can seal poly material up to 20mil in thickness (We recommend double impulse for heavy duty applications)
  • Sealers w/cutters seal and trim excess material (tubing) in order to make customized bags

Direct heat (constant heat) sealers maintain constant heat in both jaws.  Direct heat sealers use power as long as the machine is turned on.  As a result, direct heat sealers possess better heat penetration in roder to seal thicker materials.  We recommend a direct heat sealer for materials such as coated aluminum foil, poly cello films, gusset bags, coated Kraft papers, waxed paper, cellophane, mylar, coated PP, and other thicker materials.

We also include other types of sealers used for more specific types of applications:

Vacuum sealers remove air from the product before sealing into an impermeable package.  We recommend vacuum sealing in order to prevent oxidation, spoilage or corrosion.  Barrier bags are used because PP and PE bags are both porous and cannot be used for long term storage.

Clam shell sealers are ideal for welding clam shell packaging.

Size

The size of the sealer depends on the width of the material to be sealed.  We usually recommend adding one inch to the width of material to be sealed for easier handling.  Cutters on the sealer usually trim at slightly less than width of the sealer arm.

Speed
  • Portable sealers are lightweight, handy and versatile.  Sizes, however, are limited.
  • Hand sealers are the most simple and economical unit.  The sealing bar is lowered manually.  Sizes are available from 4” to 40” and approximately 6-20 packages can be sealed per minute.
  • Foot sealers provide a faster seal than hand sealers.  The sealing bar is pedestal controlled leaving your hands free.  Sizes are available from 12” to 35” and approximately 8-20 packages can be sealed per minute.
  • Automatic sealers provide even faster sealing than foot sealers and are ideal for high production jobs.  Automatic sealers are usually tabletop sealers whose jaws are activated automatically by a dial-controlled sequence timer.  Automatic sealers feature a pre-set time cycle to allow for a fully continuous automatic operation.  Automatic sealers can also be used with a foot pedal for semi-automatic operation.  Sizes are available from 12” to 47” and approximately 20-50 packages can be sealed per minute.
  • Continuous band sealers provide the fastest sealing operation with an unlimited length.  Bags are simply fed into sealer while resting on a conveyor belt.  Several models are available with features such as horizontal seal head, vertical seal head, tilting seal head, left or right feed, gas purging, and/or coding and imprinting.
Width of Seal / Packaging Material

Heating elements are made of nichrome (nickel-chromium) and determine the width of the seal.  There are two types of heating elements: round or flat which are interchangeable in most sealers. The round wire is mainly used to cut and seal with no excess material above the seal.  Depending on the width of the flat wire element, sealers are available in 2-3mm, 5mm, 8mm, or 10 mm. Some sealers are equipped with two heating elements for faster heat penetration making them ideal for sealing thicker materials.

 

Standard Features of our Impulse Sealers

The all-metal construction of our sealers provides industrial quality strength and ensures lasting durability.  The body is formed out of rugged cast aluminum while the pivot is an all-steel construction.  Most sealers are equipped with a plug-in electronic timer and built-in microswitch.  No warm-up time is needed.  The variable timer let you seal various types and thickness of plastic films.  A signal light and “beep” indicates the heat cycle is complete and the seal is done.

The number in the model number usually indicates the size of the sealer in mm; so 200 points to an 8″ sealer while 1000 points to a 40″ sealer. The letter in the model number is used to designate the manufacturer and type of sealer.  For example, “H” signifies a hand sealer while an “A” suggests auto sealer.
