Overview

The YCT-LF100 Electromagnetic Induction Aluminum Foil Sealing Machine delivers fast, reliable hermetic sealing of aluminum foil liners on screw-capped plastic and glass containers — without any contact with the bottle or cap. As each container passes under the sealing head, the induction coil generates eddy currents in the foil liner, bonding it permanently to the container neck. The result is an airtight, tamper-evident seal that preserves freshness, prevents leakage in transit, and provides visible evidence of opening.

Because the sealing head never touches the cap or foil, there is no mechanical wear and no risk of contaminating or deforming the closure. The process runs at full conveyor speed — up to 260 containers per minute — making the YCT-LF100 compatible with high-throughput filling and capping lines without becoming a bottleneck.

Handling cap diameters from 15 mm to 120 mm and compatible with PE, PP, PET, and glass containers, the YCT-LF100 covers all standard screw-cap formats. A digital power control interface lets operators adjust sealing energy for different foil thicknesses and cap materials. Built by Dongguan Yucheng Machinery Technology Co., Ltd. (YCTAUTO), the machine is engineered for continuous industrial use, with an integrated air cooling system that prevents overheating during extended runs.

Key Features & Advantages

• Electromagnetic Induction Heating — No Contact Sealing — The sealing coil never touches the cap or foil. Heat is generated directly within the aluminum foil layer by electromagnetic induction, bonding it to the container neck without mechanical pressure. This eliminates wear on the sealing head and prevents cap deformation or contamination.

• Wide Sealing Diameter Range: 15–120 mm — Accommodates virtually all standard screw-cap sizes from small pharmaceutical and cosmetic vials (15 mm) through large condiment and industrial containers (120 mm), making a single machine useful across multiple product lines.

• High-Speed Continuous Operation: Up to 260 pcs/min — Conveyor-type continuous sealing delivers throughput up to 260 containers per minute, matching the output of high-speed filling and capping equipment and preventing line bottlenecks.

• Tamper-Evident Hermetic Seal — The fused foil-to-neck seal is airtight and tamper-evident. Once the foil is bonded, it cannot be removed without visible damage, providing consumer assurance and meeting packaging integrity standards for food, pharmaceutical, and chemical products.

• Digital Power & Speed Control — Sealing power (up to 2,500 W) and conveyor belt speed are independently adjustable via the digital control interface. This allows precise calibration for different foil thicknesses, neck finishes, and container materials — ensuring complete sealing without foil burning or incomplete bonds.

• Built-In Air Cooling System — An integrated air cooling circuit continuously cools the sealing head during operation, preventing thermal overload during extended high-speed production runs. This protects the induction coil and ensures consistent sealing performance throughout the shift.

• Compatible with PE, PP, PET & Glass Containers — The contactless sealing process works with any container material that can accept a foil-lined cap. There is no thermal load on the bottle body, so even thin-wall PET bottles and heat-sensitive containers seal cleanly.

• Simple Integration into Existing Lines — The conveyor-type design allows the YCT-LF100 to be positioned directly in line between the capping machine and labeling machine without any line layout modification. Conveyor height and belt speed are adjustable to match adjacent equipment.

Technical Specifications

Applications

The YCT-LF100 is used across industries requiring hermetic, tamper-evident sealing:

• Food & Beverage — Edible oil, soy sauce, vinegar, honey, jam, seasoning bottles, bottled water, juice, energy drinks

• Pharmaceutical & Health — Capsule bottles, vitamin jars, liquid medicine bottles — tamper evidence and seal integrity are regulatory requirements

• Cosmetics & Personal Care — Cream jars, lotion bottles, toner, serums, hair care products

• Daily Chemicals — Detergent, fabric softener, floor cleaner, disinfectant

• Agricultural & Industrial — Pesticide, fertilizer, lubricant containers where hermetic sealing prevents evaporation and meets transport safety requirements

Why Choose Yucheng Machinery

• Specialized Packaging Equipment Manufacturer — Dongguan Yucheng Machinery Technology Co., Ltd. (YCTAUTO) manufactures filling, capping, sealing, and labeling machines as its core business, with deep induction sealing experience across food, cosmetic, and chemical packaging.

• True Electromagnetic Induction Technology — Unlike conductive heat sealers, the YCT-LF100 uses genuine electromagnetic induction for faster, more uniform heat distribution, enabling higher line speeds with cleaner, more consistent seals.

• In-House Quality Control — Every YCT-LF100 is tested for pull-off strength, seal uniformity across the full diameter range, and power calibration before shipment.

• OEM & ODM Capability — We customize sealing head geometry, conveyor dimensions, and control interfaces for your specific cap range and line layout.

• Complete Packaging Line Support — Yucheng also manufactures filling machines, capping machines, and labeling machines, enabling turnkey filling-capping-sealing-labeling line supply from one source.

Frequently Asked Questions

Q: Does my container need any special preparation before using this machine?

A: Your caps must have aluminum foil liners pre-applied on the inside. Most commercial screw caps for food, pharmaceutical, and cosmetic products include these liners. The container neck must be flat and smooth for a clean bond. No bottle modification is required.

Q: How do I set the correct sealing power for my product?

A: Set sealing power via the digital control panel. We provide a recommended range guide for common applications. Run 5–10 trial containers and verify seal integrity by attempting to peel the foil — a correct seal tears rather than peels. Adjust power in small increments to achieve the desired quality.

Q: Can one machine handle multiple cap sizes from the same product line?

A: Yes. The YCT-LF100 seals any cap diameter from 15–120 mm. When switching sizes, adjust the guide rails and re-confirm the power setting. No head replacement is required within the standard range.

Q: What happens if there is no foil liner in a cap?

A: No seal forms — the electromagnetic field has nothing to react with. The machine does not damage the cap or container. For lines where foil liner presence must be guaranteed, we recommend adding an upstream liner-detection sensor.

Q: What is the minimum order quantity (MOQ)?

A: The standard MOQ is 1 unit. Volume discounts are available for multi-unit orders — contact our sales team for pricing.

Q: What warranty and after-sales support is included?

A: Yucheng provides a 12-month warranty on components. The machine ships with an operation manual, wiring diagrams, and setup video. Remote technical support is available during commissioning and throughout the warranty period.

Q: Can the YCT-LF100 be positioned inline between my capping machine and labeler?

A: Yes, this is the standard configuration. Conveyor height and speed are adjustable to match adjacent equipment. Contact us with your line layout drawing for integration guidance.
