Ultrasonic dot-line sealer L-QP-01

Ultrasonic Dot-Line Sealer L-QP-01

Seal plastic bags, non-woven fabrics, and other thin materials cleanly — without staples, rubber bands, tape, or glue. The L-QP-01 uses ultrasonic vibration to weld materials shut along a dotted line, giving you a fast, consumables-free alternative to conventional bag closing methods.

Why choose ultrasonic sealing

• No contamination risk — since no staples, bands, or tape are used, there's nothing that can accidentally end up inside the package.
• Clean appearance — leaves only a small, neat weld mark instead of disrupting the package with visible fasteners.
• Easy to position — the handpiece's arc-shaped teeth make the sealing point easy to see, so the operator can weld exactly where intended.
• Fast and simple to operate — turn on the power, set the timer, and slide the handpiece horizontally while gripping the material to seal.
• Strong weld — repeated multi-directional vibration produces a secure bond.
• Easy-open packaging — sealed packages open cleanly from the end of the dotted-line seal point.
• Worldwide voltage compatibility — runs on 100–240V AC, 50/60Hz.
• Made in Japan — manufactured in Nagoya, Japan.

Applications

• Bagging and subdivision packing (e.g. small parts, hardware)
• Repackaging (e.g. produce, retail goods)
• Temporary fastening in sewing and non-woven fabric work
• Sealing nylon bags, non-woven material, bubble wrap sheet, and aluminum bags

Compatible materials: PSP, OPS, PVC, HIPS, PPF, PP, and A-PET (compatibility varies by material combination — see compatibility chart).

Note: This machine is not intended for airtight sealing.
