Whether you're closing a few dozen plastic bottles or capping parts on a factory floor, the machine you pick depends on volume, bottle material, and how much space you have. Capping and sealing may sound interchangeable, but production-scale capping and portable induction sealing serve completely different workflows. The right choice comes down to whether you need a stationary conveyor system, a heavy-duty machine, or a handheld sealer you can store in a drawer.
Quick take
- The WHITE SWAN-MATIC MASTER is the only capper in this group, built around a single-cycle capping function.
- The 20-100mm Automatic Sealer is an automatic induction sealer rated for 10-30 pcs/min.
- Both handheld induction sealers share a 2-10cm sealing diameter; the lower-priced listing also includes spare bottles and a spare button.

Product notes
WHITE SWAN-MATIC BOTTLE CAPPING MACHINE MASTER
The WHITE SWAN-MATIC MASTER is the production-level choice in this group. It's a used 2014 semi-automatic machine with 25 hp spindle horsepower, 115/230V operation, and a single-cycle capping function. If you're applying caps in a repeatable manufacturing step and need a machine that can handle a demanding role, this is the one that fits that description. At USD 4,000, it carries the highest listed price. It is not a benchtop sealer, and the used condition and industrial power draw make it best suited to a dedicated facility rather than a small workshop.
20-100mm Bottle Cap Automatic Sealer Continuous Induction Sealing Machine 1800w
This automatic sealer is designed for continuous work. The 1800w unit uses three pure copper induction coils and an air-cooled design, with efficiency listed at 10-30 pcs/min. The conveyor table measures 135*49*10cm, and the adjustable guards help keep bottles in position as they move through the sealing head. Construction is 304 stainless steel. The listed price is USD 597.56. It requires bench space and fits bottles up to about 11.81in in height, so it's not a handheld tool. Choose it when you want a steady flow of sealed bottles rather than one-at-a-time manual sealing.
Handheld Induction Sealer Electromagnetic Heating Plastic Bottle Sealing Machine Handheld (USD 70.14)
This compact handheld unit brings induction sealing to a countertop. It uses electromagnetic induction to heat and laminate aluminum foil on non-metal bottles, with a sealing diameter range of 2-10cm. The DGYF-880 runs on U.S. 110V and has adjustable power levels, so you can dial in the output. Its strength is portability: you can hold the sealer over each cap without lifting a bottle onto a conveyor. The limitation is purely manual pacing, and it's not suitable for metal bottles. At USD 70.14, it offers a dedicated handheld option with a separate price point from the kit version.
Handheld Induction Sealer Electromagnetic Heating Plastic Bottle Sealing Machine Handheld (USD 61.15)
The least expensive listing in this comparison is also a handheld induction sealer. It shares the DGYF-880 model and the same 2-10cm sealing diameter, with a U.S. 110V plug. What sets this listing apart is the package contents: it includes one spare button, two bottles, and a user manual. That makes it a convenient starting point if you want to test induction sealing right away. The trade-off is the same as any manual handheld unit: you'll work bottle by bottle, and it's meant for non-metal containers. At USD 61.15, it's the entry-priced handheld in this lineup.
Final recommendation
When you line these up by use case, the choice is clear. If you need a semi-automatic capping machine with substantial power, the WHITE SWAN-MATIC MASTER is the only option that caps rather than seals. If you need continuous bottle sealing with a conveyor and can accommodate a bench-top unit, the 20-100mm Automatic Sealer delivers a steady throughput. If your bottles are non-metal and you only need occasional sealing, either handheld sealer can work. Pick the USD 61.15 model if you want the spare bottle and button included, or the USD 70.14 model if you prefer a handheld unit without the extra pieces. Your bottle material and daily volume are the deciding factors.
