The Ultrasonic sealing machine tubes filling equipment model YX-UF100B is linked with ultrasonic sealing, the heat required for melting is only generated inside the thermoplastic sealing layer. For localized conversion of vibrations to friction heat, the anvil or sonotrode profiles are mostly linear and include radii or small plateaus. These profiles ensure focusing of the energy input and therefore short sealing times between 100 and 200 milliseconds. With ultrasonic sealing heat is generated at the inside of the film, not by heat input from the outside as is the case with heat sealing, for example. The tools (sonotrode and anvil) that come into direct contact with the packaging material, remain cold during the entire weld process. The support layer remains almost cold and upon termination of energy input, the heat dissipates faster to the outside due to the temperature difference between the support layer and the sealing layer so that the hot-tack resistance is significantly higher.

Ultrasonic sealing is particularly well suited for:

►Thermoplastic films (pouches and bags) Tubes, trays, and cups

►Tubes, trays, and cups

►Cardboard packaging with thermoplastic coating

►Valves and vents on films / filter materials

►Screw caps on coated cardboard packaging / films

When choosing tube filling equipment for plastic tubes, it is very important to understand the various types of tube sealing options available.  Tube filling machinery comes with hot-air sealing, ultrasonic sealing, impulse sealing or hot-jaw sealing options.  Matching the type of squeeze tube with the correct tube sealing equipment is very important to ensure strong, professional tube seals.  Each tube material behaves differently so what works well for a mono layer polyethylene cosmetic tube, may not work so well with a multi-layer COEX tube.  Depending on the industry for a given product, such as cosmetic tubes, personal care tubes, pharmaceutical tubes, or household & industrial tubes, choosing the correct tube filling & sealing equipment can be challenging.  Lets take a look at the two most popular options currently used in the tube packaging industry today.

Hot Air Tube Sealers

The most popular tube sealing machinery option is hot-air tube sealing.  With this system hot air is generated and blown into the open end of the plastic or laminate tube.  This heated air penetrates the plastic tube wall heating the material enough to make it soft and pliable.  A set of tube sealing jaws then crimps the softened plastic to weld the open end closed.  The primary advantage of this tube sealing technology is it’s speed.  Another advantage is hot air sealers work with the largest range of laminate or plastic tubes.  Whether the tube material is LDPE, MDPE, HDPE, PP, Mono layer or multi-layer with or without EVOH barrier protection, hot air tube sealing should work.  A disadvantage however is the need for specific hot air nozzles sized to each diameter tube that is filled and sealed.  This will add to the cost of change parts needed for the tube run.  The cost of format parts are minimal however when factored over the production run size at higher throughput.  We recommend this style of tube filler if the production run sizes are greater than 20,000 tubes.

Ultrasonic Tube Sealers

Ultrasonic tube sealing is another popular option found in the packaging industry today.  Standalone tube sealers using ultrasonics are popular for small volume tube runs.  Tube filling machinery can also be retrofitted with ultrasonic tube sealing systems as an alternative to hot air sealing.  With ultrasonic tube sealing, plastic and laminate tubes are sealed by high frequency vibration of an ultrasonic sealing horn.  This high frequency vibration generates intense heat at the tube wall which causes the polyethylene tube plastic to soften.  The open end of the plastic tube is held closed under pressure from the sealing horn and matching sealing anvil, thus forming a strong weld.  Advantages of sealing tubes with ultrasonic technology are the ease of use, no need for custom-made size parts, and ability to seal through product contamination in the seal area such as happens when overfilling a tube with product.  The disadvantage however is lower tube sealing speed compared to hot-air sealing.As far as our ultrasonic sealing machine model YX-UF100b is concerned,the basic information given as below:
