Product Details
Ultrasonic heat sealed flat pocket, also known as bone sealed packaging bag
The core features are firm sealing, clean edges, efficient production, controllable cost, wide material adaptability, flexible application, lightweight design, and easy portability.
The ultrasonic heat sealing process does not require needle or thread, and uses high-frequency vibration to heat and fuse the material itself. The edges are smooth and free of burrs, and the sealing performance is better than that of ordinary sewing bags, which can effectively prevent small objects from falling off inside; At the same time, it avoids the problem of excessive breathability caused by needle and thread holes, making it suitable for storing items that require light dust prevention (such as jewelry and small tools).
Ultrasonic heat sealing belongs to automated processing technology, with fast production speed and suitable for mass production. Compared with manual sewing, it can reduce processing costs. Therefore, under the same specifications, the price of ultrasonic heat sealing flat pockets is more competitive.
Mainly suitable for non-woven fabrics (PP spunbond, PET, etc.), and can also be used for some film materials (such as PE, composite film); The flat mouth design is simple and can be customized in size according to needs. It can be used as an inner packaging (such as dust bags for clothing and towels), as well as a daily storage bag (such as stationery and cosmetics sample packaging).
Flat mouth without three-dimensional expansion structure, overall lightweight, empty bag can be folded flat without occupying space; The load-bearing performance of the edge heat joint is moderate (conventional models can bear 1-3kg), suitable for storing lightweight small items.
