Sealer Pro, Patented 16inch Impulse Heat Bag Sealer, 5mm Sealing Width Poly Bag Seal Machine, 2 Replacement Kits 1 Extra Fuse Included, Black

This is a wonderful, substantial, sturdy, easy to use sealer. Sealed my Mylar bags, easy as pie. Great customer service too, I had a question about the replacement kit and received a quick and thorough reply. I am definitgely happy that I chose this quality sealer, I have a lot of sealing to do and I know my reliable new LinsnField Sealer is going to get the job done.

I love this product. It is better than any other heat sealer I have used, and it comes with lifetime warranty. If your machine breaks down, just contact Linsnfield and they will make it good for you. One thing you should notice is that when you buy replacement parts (the heating wire and the PTFE Teflon Heat Resistant Cloth) you need to buy the one that is specifically made for Linsnfield heat sealer, otherwise they won't fit. Other than that it is a great product.

I got this to make some custom size meal prep and sous vide bags. The main reason was I wanted some small bags for frozen smoothies. There were some options on small bags but I didn't want to spend double the money on 1000 bags not knowing if they would be the right size. I can make custom bags with my FS but after 4 seals in a row it goes into cool down for 30s. This thing is a beast when it comes to multiple runs. I just set up and sealed over 100 custom 2x10 bags with no pause and no problems. I know I saw a few other machines that people had issue with having to keep increasing the time when sealing back to back but not this one. I actually turned it down once the heads were warmed up and never touched again. You can barely tell the difference between the factory seal and this, other than my jagged cutting

The assembly of the first unit I received was deeply concerning: the LED indicator did not come on, and the heating element did not heat up. I opened the bottom panel (which was installed upside down) and saw that the impulse timer was not connected to the circuitry in any way, and the wires which should connect to the timer were connected to each other with yellow heat shrink tubing (see top unit in photo). I believe the first unit I received was a returned unit which was "repaired" by an unscrupulous technician. I noticed the first unit was shipped without the original packaging, and did not include the extra heating elements and fuses. The replacement unit arrived with original packaging and included the extra items... And it is fantastic! I purchased this model to replace the last slightly less expensive model I had purchased and returned. The aluminum housing is much more robust than the previous model, which had a thinner metal/iron housing. The thinner housing created issues with the screw holes stripping. The copper transformer is huge compared to the last model, which was much less powerful. I measured the wattage using a smart power strip, and this model pulls approximately 850 Watts, compared to the last model's meager 280 Watts. Note that this is higher than the wattage listed in the description and on the side of the unit, but for my purposes that is a good thing. The heavier duty grounded cord/plug on this unit gives added peace of mind. This unit is a great value. Other vendors are selling similar units for almost twice the price, or more. Expect to see some minor cosmetic defects, and you may want to do some tweaking. The arm isn't always aligned perfectly. There is a small pin on the housing which mates with a hole in the arm bracket to align the arm during factory assembly, but the fit of the pin on the hole is not tight enough to ensure perfect alignment. The metal tab which depresses the mechanical "ON" switch can travel too far when depressing the arm with pressure, causing it to push against the housing of the switch and displace it slightly. These issues are likely present in any of the similar impulse sealers available. More industrious/neurotic customers will be able to adjust things to their satisfaction. The bolts securing the arm can be adjusted from inside the unit with a socket wrench to align the arm, and the travel of the metal tab can be adjusted by bending it slightly to engage the switch at the desired pressure without pushing against the switch housing. I recommend this impulse sealer for use with grain spawn bags. It seals 3 mil gusseted (4 layers) polyethyene grain spawn bags perfectly at the 4 second setting. I haven't tried polypropylene bags, or thicker 6 mil bags.

The kit comes with some spare cloths and springs, which is a nice touch because depending on what you're sealing it can get dirty quickly. I use this mainly for shrink rap and sealing bags (plastic and mylar). The power setting is helpful to have to adjust for the material you're using. It only heats up while depressed so the first cold press takes nearly double the time (4sec) on a mylar bag seal than it does for bags 4,5,6 (2 sec) once the metal elements warm up a bit between sealing presses. I've used it for thousands of bags without any issues with the switch or fuses, or really any main complaints.
