Nut food packaging bag is a small classification of dried fruit packaging bags, nut packaging bags include walnut packaging bags, pistachio packaging bags, sunflower seed packaging, etc. Compared with other dried fruit packaging bags, nut food packaging bags have the following characteristics:
1, flexible and resistant to puncture, to prevent the nut food hard shell to puncture the packaging bag.
2, the packaging is more high-grade, highlighting the high nutrition and grade of nut food.
Three sides sealed nuts bag, left and right are sealed, the upper part is hot sealed 1 to 2 cm. The customer puts the nut food into a trilateral sealing bag from the bottom, and then hot seals the plastic packaging mouth.
Side gusset nut packaging bag, this is the nut sunflower seeds use the most bag type, left and right sides, large capacity, exquisite shape.
Eight-side sealed nut packaging, this bag type has a three-dimensional sense, can stand on the shelf, convenient sales shelf, consumer consumption. On the side, the bottom has three planes for color printing food packaging information, eight zipper bag with reusable zipper, consumers can open and close the zipper, the box can not compete; it is conducive to promote the brand and attract consumer attention.
Self-reliance bag in nut food, can be self-supporting, usually with a zipper, can be used repeatedly, easy to carry.
1. Production procedures
1. Prepare: install the transverse hot sealing knife, the bottom hot sealing knife, strengthen the hot sealing knife, and install the punching device.
2. Wear the film, set the EPC, and align with the bag edge and pattern.
3, adjust the bottom of the hot sealing knife, input length and size, the position direction of the knife should be flat, the above knife is the reference knife, check whether the round hole is round. Set up the photoelectric sensor.
4. Install the bottom film and adjust to fold in the middle. Bottom film punching.
5. Adjust the horizontal heat seal to align the position of the heat seal knife and the printing position.
6. Adjust and strengthen the heat sealing block, and fill the pressure at the intersection of the four layers.
7, adjust the cutting knife, the edge material cutting device.
8. Confirm and adjust the bottom surface punching position and the hot sealing position of the bottom surface. Confirm and adjust the position of transverse and reinforcing heat sealing block. Confirm the thermal seal strength and adjust the thermal seal temperature.
2. Production points
1, the bottom membrane tension should not be too high. The tension is too high, the bottom round hole will deform. General tension force 0.05~0.2MPa.
2. The first group of hot sealing knife has higher pressure and lower temperature, and the second and third groups use normal temperature and pressure.
3. The spring pressure of the heat sealing block is adjusted to zero, so that the weight of the heat sealing device plays a role.
4, silicone board generally with hardness of 50°, sealing area is small to use 70° plate.
5. During hot sealing, the round hole on the bottom surface can increase the waiting time by 100min.
6. The bag-making speed is generally 50~100 bags per minute.
