Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging films, in particular to a plastic packaging film for agricultural harvesting machinery. Background Art

[0002] Plastic wrapping film plays a very important role in agricultural harvesting equipment. It is mainly used to wrap crops such as hay, cotton, silage or corn to protect them from sunlight, rain and oxygen erosion. This film has the functions of waterproof, heat preservation, degradation, windproof and breathable, which can extend the storage time of crops in the field, thereby improving harvesting efficiency and reducing losses. During use, farmers can use a special wrapping machine to quickly and evenly wrap the film on the surface of the crop to ensure the tension and sealing of the film. At the same time, in order to facilitate subsequent harvesting and transportation work, the wrapping film can also be simply cut and unwrapped as needed.

[0003] In the related art, in order to facilitate the rolling of the packaging film, the packaging film is cut into multiple small sections. However, in order to roll up the multiple small sections, a connecting adhesive layer is required at one end of each section of the packaging film to bond the adjacent section of the packaging film, and the multiple sections of the packaging film are bonded into a whole. The entire packaging film is rolled up and installed in an agricultural harvesting machinery for standby use. However, only using the adhesive layer for connection can easily cause the connection position to be damaged when the packaging film is pulled out, and there is a problem of offset of the single film during rolling and transportation. Utility Model Content

[0004] The main purpose of the utility model is to provide a plastic packaging film for agricultural harvesting machinery, aiming to make the packaging film convenient to use.

[0005] To achieve the above-mentioned purpose, the utility model proposes a plastic packaging film for agricultural harvesting machinery, comprising several packaging film sheets connected end to end for rolling into a roll, wherein the packaging film sheets are sequentially provided with a no-glue area, a low-viscosity glue area and a high-viscosity glue area, wherein the high-viscosity glue area is arranged at the tail of the packaging film sheet, and a traction release film is arranged at one end of the packaging film sheet away from the low-viscosity glue area in the no-glue area; the high-viscosity glue area of ​​the previous packaging film sheet is connected to the no-glue area of ​​the next packaging film sheet through the traction release film.

[0006] Preferably, the traction release film includes a folded back layer, a release film is further arranged between the folded back layer and the high viscosity adhesive area of ​​the previous packaging film sheet, the folded back layer and the release film are connected through the adhesive area, and the release film and the high viscosity adhesive area are adhered to each other.

[0007] Preferably, the traction release film further comprises a traction release film block, one end of which is connected to the adhesive-free area of ​​the subsequent packaging film sheet by adhesive, and the other end of which is integrally formed with the folding back layer.

[0008] Preferably, both ends of the packaging film sheet are provided with edge trimming areas, and the edge trimming areas are arranged in a shape that gradually narrows from the center of the packaging film sheet toward the end.

[0009] Preferably, both sides of the packaging film are provided with edge binding areas, the edge binding areas on both sides are arranged opposite to each other and cover the side edges of the non-glue area, the low-viscosity glue area and the high-viscosity glue area.

[0010] Preferably, a stop label is provided on the packaging film, and the stop label is arranged in the low-viscosity glue area and is located at one end close to the high-viscosity glue area.

[0011] Preferably, one or more RFID traceability tags are provided on the glue-free area.

[0012] Preferably, a tear line is provided at the connection between the front packaging film sheet and the rear packaging film sheet.

[0013] Preferably, the area of ​​the non-glue area is larger than that of the low-viscosity glue area, and the area of ​​the low-viscosity glue area is larger than that of the high-viscosity glue area.

[0014] The technical solution of the utility model forms a roll of packaging film by connecting the tails of multiple sections of packaging film sheets. In order to ensure that the roll of packaging film can be stably installed in agricultural harvesting and convenient to use, the packaging film sheet includes a non-glue area, a low-viscosity glue area and a high-viscosity glue area, and the three glue areas are arranged on the packaging film sheet in sequence, the non-glue area is located at the head of the packaging film sheet, the low-viscosity glue area is located in the middle of the packaging film sheet, and the high-viscosity glue area is located at the tail of the packaging film sheet. A traction release film is arranged at the non-glue area corresponding to the high-viscosity glue area. The traction release film can be connected to the non-glue area by an easy-tear line, and can also be connected to the non-glue area by a sticky glue. The high-viscosity glue area is connected to the traction release film to ensure the stable connection of the two packaging film sheets. The easy-to-separate structure design of the traction separation film can make the separation of the two packaging film sheets smoother and more convenient. The purpose of setting the no-glue zone is to prevent the wrapped object from being contaminated by glue during the wrapping process. The no-glue zone is set according to the size of the package. The low-viscosity glue zone is set after winding for one and a half weeks. The low-viscosity glue zone is set to adhere to the no-glue zone, reduce the expansion coefficient, and wrap the wrapped object tighter and stronger.

[0024] Reference Figures 1 to 4 In one embodiment of the utility model, a plastic packaging film for agricultural harvesting machinery is proposed, comprising several packaging film sheets 1 connected end to end for rolling into a roll, the packaging film sheet 1 is provided with a non-glue area 2, a low-viscosity glue area 3 and a high-viscosity glue area 4 in sequence, the high-viscosity glue area 4 is arranged at the tail of the packaging film sheet 1, and a traction release film 5 is arranged at one end of the packaging film sheet 1 away from the low-viscosity glue area 3 at the non-glue area 2; the high-viscosity glue area 4 of the previous packaging film sheet 1 is connected with the non-glue area 2 of the next packaging film sheet 1 through the traction release film 5.

[0025] In a plastic packaging film for agricultural harvesting machinery of the present application, multiple sections of packaging film sheets 1 are connected at their tail ends to form a roll of packaging film. In order to ensure that a roll of packaging film can be stably installed in agricultural harvesting and convenient to use, the packaging film sheet 1 includes a non-glue area 2, a low-viscosity glue area 3 and a high-viscosity glue area 4, and the three glue areas are arranged on the packaging film sheet 1 in sequence, the non-glue area 2 is located at the head of the packaging film sheet 1, the low-viscosity glue area 3 is located in the middle of the packaging film sheet 1, and the high-viscosity glue area 4 is located at the tail of the packaging film sheet 1, and a traction release film 5 is provided at the non-glue area 2 corresponding to the high-viscosity glue area 4. The traction release film 5 can be connected to the non-glue area 2 of the packaging film sheet 1 near the easy-tear line, and the high-viscosity glue area 4 is connected to the traction release film 5 to ensure the stable connection of the two packaging film sheets 1, and the easy-to-separate structure design of the traction release film 5 can make the separation of the two packaging film sheets 1 smoother and more convenient.

[0026] When wrapping an article, first wrap the outer surface of the article with the non-glue area 2, and then the packaging film 1 continues to wrap the article. At this time, the low-viscosity glue area 3 will be wrapped around the outer surface of the non-glue area 2 to fix it. Then the packaging film 1 continues to wrap the article, and the high-viscosity glue area 4 will be wrapped around the outer surface of the low-viscosity glue area 3 to seal it.

[0027] The glue-free area 2 is used to prevent the wrapped object from being contaminated by glue during the wrapping process. In this embodiment, the glue viscosity of the low-viscosity glue area 3 is weaker than that of the high-viscosity glue area 4. The glue strength of the two is relative and is not limited to a specific value.

[0028] Combined with reference Figure 3 to Figure 4 In one embodiment of the present application, the traction release film 5 includes a folding layer 51, and a release film 52 is further provided between the folding layer 51 and the high-viscosity adhesive area 4 of the previous packaging film sheet 1. The folding layer 51 and the release film 52 are connected through the adhesive area 54, and the release film 52 is adhered to the high-viscosity adhesive area 4. An easy-tear line is provided at the connection between the previous packaging film sheet 1 and the next packaging film sheet 1, and the traction release film 5 can be connected to the adhesive-free area 2 of the packaging film sheet 1 near the easy-tear line.

[0029] Combined with reference Figures 2 to 4 In one embodiment of the present application, the traction release film 5 also includes a traction release film block 53, one end of the traction release film block 53 is connected to the glue-free area 2 of the subsequent packaging film sheet 1 by adhesive glue, and the other end is integrally formed with the folding layer.

By providing the traction separation film block 53, the two packaging film sheets 1 can be separated more conveniently while facilitating the bonding of the front and rear two groups of packaging film sheets 1, thereby avoiding damage to the rear packaging film sheet 1 due to the excessive viscosity of the high-viscosity glue area 4 when separating the packaging film sheets 1.

[0031] Combined with reference Figures 1 to 4 In one embodiment of the present application, both ends of the packaging film sheet 1 are provided with edge trimming areas 7, and the edge trimming areas 7 are arranged in a shape that gradually narrows from the center of the packaging film sheet 1 toward the end.

[0032] In a plastic packaging film for agricultural harvesting machinery of the present application, both ends of the packaging film sheet 1 are provided with edge trimming areas 7, and the edge trimming areas 7 are narrowed from wide to a reasonable size for the equipment used, mainly to solve the problems of smooth film feeding, smooth outer edge trimming on both sides, sealing and bonding of objects after wrapping, and longer storage time.

[0033] Combined with reference Figures 1 to 4 In one embodiment of the present application, both side edges of the packaging film 1 are provided with edging areas 6, and the edging areas 6 on both sides are arranged opposite to each other and cover the side edges of the non-glue area 2, the low-viscosity glue area 3 and the high-viscosity glue area 4.

[0034] In a plastic packaging film for agricultural harvesting machinery of the present application, two sets of edge wrapping areas 6 are arranged on the side of the packaging film sheet 1, so as to facilitate more perfect folding of the two sides during use, and objects after the edges are wrapped are not easy to fall off or get water in, which is more conducive to wrapping the wrapped objects more firmly.

[0035] Combined with reference Figure 1 In one embodiment of the present application, a stop label 8 is provided on the packaging film 1 , and the stop label 8 is arranged at the end of the low-viscosity glue area 3 close to the high-viscosity glue area 4 .

[0036] In the agricultural harvesting machinery plastic packaging film of the present application, a stop label 8 is set at the rear of each unit piece wrapping film. When in use, the automatic harvesting equipment senses the stop label and separates the previous packaging film from the next packaging film.

In the present embodiment, a plurality of RFID traceability tags 9 are arrayed in the glue-free area 2. This is because the thickness of the low-viscosity glue area 3 will increase due to the glue layer. Thus, arranging the RFID traceability tag 9 in the glue-free area 2 can facilitate the use of the traceability tag more conveniently. Of course, arranging the RFID traceability tag 9 in the low-viscosity glue area 3 or other positions can also work normally.

[0040] In a plastic packaging film for agricultural harvesting machinery in the present application, the traction separation film 5 is connected to the glue-free area 2 through the high-viscosity glue area 4. The high-viscosity glue area 4 is directly arranged on the glue-free area 2 when the packaging film sheet 1 is produced. In this way, the high-viscosity glue area 4 can be very tightly bonded to the traction separation film 5 and the glue-free area 2. The tail heads are bonded and compounded into a roll using automated composite equipment, which is convenient for better use on automatic harvesting machinery and for convenient storage. At the same time, when adjacent packaging film sheets 1 need to be separated, it is faster and more stable, and it is not easy to damage the packaging film sheet 1, making the use of the entire packaging film more convenient.

[0041] Combined with reference Figure 1 In one embodiment of the present application, the area of ​​the non-glue region 2 is larger than the area of ​​the low-viscosity glue region 3 , and the area of ​​the low-viscosity glue region 3 is larger than the area of ​​the high-viscosity glue region 4 .

[0042] It should be noted here that the area of ​​the non-glue area 2, the area of ​​the low-viscosity glue area 3, and the area of ​​the high-viscosity glue area 4 can be set as needed. In order to facilitate the operation when wrapping items and ensure tight and reasonable wrapping, the above setting method is preferred.
