Embodiment 1

[0058] On-line laminating process to produce surgical tray bagging (heat bonding method, free of hot melt adhesive, hydrosol, reactive glue or double-sided tape, etc.)

[0059] The casting and bonding process steps of this embodiment are as follows:

[0060] (1) According to the formula of the tubular film layer 1, weigh the raw materials from the weighing device 4, then add them to the high-speed mixer 5 and mix them evenly, then send them from the hopper 6 to the casting machine 7 for heating and melting, and then from the casting machine The T-shaped die head 8 of 7 flows out and casts into a flat film 9. When the flat film 9 is still in a molten state, the absorbent layer roll material 10 is conveyed to the flat film 9 by a conveyor belt to be bonded, and then pressed, cooled, solidified, Molding is made into a flat film with an absorbent layer; in this step, the device for lamination is at least: a steel rod 11 and a rubber roller 12, and the flat film 9 and the absorbent...

Embodiment 2

[0065] Production of surgical tray sleeves by in-line bonding of absorbent layers (gluing with hot-melt, hydrosol or reactive glue, etc.)

[0066] The casting and bonding process steps of this embodiment are as follows:

[0067] (1) According to the formula of the tubular film layer 1, weigh the raw materials from the weighing device 4, then add them to the high-speed mixer 5 and mix them evenly, then send them from the hopper 6 to the casting machine 7 for heating and melting, and then from the casting machine The T-shaped die head 8 of 7 flows out and casts into flat film 9. After the flat film 9 is cooled and solidified, glue gun 18 is used to spray glue 19 on-line, and at the same time, the cut absorbing layer 2 is transported to the appropriate position for spraying glue 19 with a conveyor belt, and then the flat film 9 and the absorbing layer 2 are bonded together; The length, width and position of the absorbing layer 2 can be adjusted according to product requirements....

Embodiment 3

[0071] Production of surgical tray bagging by laminating the absorbent layer offline (by manual lamination)

[0072] The casting and bonding process steps of this embodiment are as follows:

[0073] (1) According to the formula of the tubular film layer 1, weigh the raw materials from the weighing device 4, then add them to the high-speed mixer 5 and mix them evenly, then send them from the hopper 6 to the casting machine 7 for heating and melting, and then from the casting machine The T-shaped die head 8 of 7 flows out and casts into flat film 9. After the flat film 9 is cooled and solidified, the films on both sides are folded by a triangular folding machine 13 or other folding devices (such as Figure 9 shown), and then enter the heat-sealing machine 14 for heat-sealing. The overlapping size of the heat-sealing edge can be adjusted between 0.1-5cm according to product requirements, preferably 0.5-1cm. The heat-sealed film material is in the form of a tube and rolled up, t...

Abstract

The invention relates to a surgical tray cover bag and a preparation method for the same. The surgical tray cover bag comprises a tubular thin film layer, wherein one end of the tubular thin film layer is sealed, and the other end of the tubular thin film layer is opened; an absorption layer is attached to the outer surface of the tubular thin film layer; one end of the absorption layer is close to the closed end of the tubular thin film layer, and the other end of the absorption layer extends to the other end of the tubular thin film layer or any position of the middle part of the tubular thin film layer; the tubular thin film layer is a tubular thin film which is formed by folding and heat-sealing a flat film prepared by a tape-casting process. According to the surgical tray cover bag and the preparation method for the same, the tubular thin film is prepared by the tape-casting process, so that the shortcomings of low productivity, high cost and the like of a conventional film blowing process are overcome, and a product is high in competitiveness.

Description

technical field [0001] The invention relates to a surgical tray bag and a preparation method thereof. Background technique [0002] Surgical tray cover is also called "Medical Mayo stand cover (MSC: mayo stand cover)". It is an absorbent layer, which has the function of absorbing blood, body fluids, medicines and other liquid substances remaining on surgical instruments. [0003] Traditional surgical tray bags (such as figure 1 shown) is to use a tubular film 1`, and attach an absorbent layer 2` on one side of the tubular film 1`, one end of the tubular film 1` is heat-sealed and the other end is open, as figure 1 For the shown heat-sealing line 3', for the convenience of use, the other end of the tubular film is folded outwards to form a bag opening, and the folded length is a'. The traditional tubular film 1` of surgical tray bagging is prepared by blown film process, but the blown film process has the disadvantages of low production capacity and high cost, resulting in...
