Embodiment 1

[0026] A composite packaging film for welding rods, consisting of a surface layer, a middle layer and a bottom layer, the thickness of the surface layer is 0.011-0.013mm, the thickness of the middle layer is 0.011-0.013mm, the thickness of the bottom layer is 0.10-0.12mm, the surface layer is composed of PA, and the middle layer is composed of LLDPE and MLLDPE Composition, the weight ratio is 49-51:49-51, the bottom layer is composed of LLDPE and MLLDPE, the weight ratio is 39-41:59-61.

Embodiment 2

[0028] A preparation method for a composite packaging film for welding rods, comprising the following steps:

[0029] ① prepare each layer of raw materials by the proportioning of embodiment 1.

[0030] ② Feed the raw materials prepared in Example 1 into the extruder, melt and plasticize at a temperature of 230°C, and then flow into the die head through the distributor according to the weight ratio, and the production speed is 55m / min. Temperature is 15-18 ℃), automatic thickness measurement and adjustment (thickness ratio of each layer is the thickness ratio in embodiment 1), film electronic shock (requires 44 dynes) winding, packaging after slitting is finished product.

[0031] The parameters not mentioned in the preparation process are the parameters disclosed in the prior art.

Embodiment 3

[0033] The composite encapsulation film that embodiment 2 is made sends to Sichuan Provincial Institute of Product Quality Supervision, Inspection and Testing for detection, and the detection results are as follows in Table 1:

Abstract

The invention discloses an encapsulation method of a plurality of 5kg electrodes. The method uses a composite film to carry out encapsulation. Compared with the existing composite film, the composite encapsulation film can be applied to the automatic 5kg electrode encapsulation, and the product qualified rate is high.

Description

technical field [0001] The invention relates to the field of welding rod packaging, in particular to a method for packaging 5kg and several welding rods, a composite film and a preparation method thereof. Background technique [0002] Since each pack of welding rods weighs 5 kg, each pack of welding rods with specification 3.2 is about several (single weight is about 33 grams). Therefore, ordinary welding rods produced in my country are hand-packed in paper bags at present. [0003] On the one hand, manual packaging of paper bags has high labor costs and high labor intensity, and the material cost of welding rod paper bag packaging is higher. [0004] On the other hand, due to the following reasons, the automation of paper bag packaging welding rods cannot be realized at present: ① After the welding rod is 5 kg, the shape after natural placement is irregular; ② The size of the paper bag cannot be larger than the standard size. ③Paper bag bonding cannot be completed within o...
