6.         Unique Design Features:

6.1    Full width pressure sealing & chilling of seal area technique Has been adopted to provide extra seal strength without Bonding surface fracture of the sealing area.

With the above said technique, the machine is capable of making liquid pouch, oil pouch, ghee pouch, vacuum or gas flashed pouches. Also, extra shelf life is achieved due to continuity of  molecular bonding in the sealing area.

6.2    Adequate nos. Of electronic sensing device has been provided at each end of the machine, one to register-cut hole punch for standi-bottom, and to register pattern sealing for different type of pouches
Another sensing device is for registered bottom sealing, v-notching & pouch shear cutting.
6.3    Low-expansion alloy steel has been provided for zip, top & side sealing. brass patterned Sealer has been provided for standi bottom sealing.

6.4    Every unwind unit operation has been made user friendly by employing individual Powder brake tension control system, centering device & auto dancing system Accumulator together with non contact sensing device and control system for compensating different type of web feeding, A.C geared motor pulling section with frequency drive and auto control.

6.4.1 Main unwind roll mounting is of horizontal type and housed in a compact heavy-duty Frame-work having easy parent roll mounting features; pull roll unit; dancing system; Web-slitting section m-plate features with adjuster roll.

6.4.2    Two sets of standi bottom strip unwind section each with self contained pulling, Pneumatically controlled dancing, electronically control system and folding System has been provided.

6.5 Web Draw Sections:

6.5.1 Intermittent and measured feeding of web of all draw-section is indexed through Servo motor & digital drive system.
6.5.2 Each continuous unwind-web pulling is done through individual a.c geared motor And individual a.c frequency drive.
6.5.3 Each continuous feeding from unwind-web and the intermittent processing on the machine are balanced & synchronized through non-contact sensors and closed-loop pneumatically operated dancing system.

6.6 Sealing & Chilling Section:

6.6.1. Sealing stations are so designed that the sealing variables (namely: dwell time, temperature and sealing pressure) are adjustable as per pouch requirement.

6.6.2  All top sealing & chilling stations are operated by specially designed cam sets.

6.6.3    Each sealing & chilling sets can be moved longitudinally for initial register setting through a rack and pinion arrangements.

6.6.4    The newly designed sealers are so designed that heater body are not changed but sealer strips are changed as per pouch requirement.

6.6.5    Chilling units are connected through distributor chamber for each chilling section.

6.7    Registered Cutting:

6.7.1    Scissors-cut action has been provided to clean cut the pouch.

6.7.2    Top cutter is set at an angle and pivoted at the ends and set against the bottom fixed cutting knife-edge by adjustable spring pressure.
6.7.3    By adjusting the spring pressure, pouch up to 250 um thick film also can be cut.
6.7.4    The life of knife has been greatly increased due to scissor- action and soft cutting load of the top knife
6.8    One sets of full width anti-static bar has been provided to eliminate static from the plastic-web.

6.9    Pouch Tear Knotching Unit:
