Cotton packaging film with high tensile strength and machining method of cotton packaging film

Abstract

The invention discloses a cotton packaging film with high tensile strength and a machining method of the cotton packaging film. The cotton packaging film with high tensile strength specifically comprises a first cotton packaging film body, a second cotton packaging film body, thin film adhesive tape and a heat sealing line. The following machining method is further included. The machining method includes the steps that S1, splicing is conducted; S2, gluing is conducted; and S3, heat sealing is conducted. During machining, after two layers of films are spliced and glued, a specially-made heat sealing probe is used for carrying out line heat sealing or multi-point heat sealing on the lower-layer splicing position along the heat sealing line, and therefore the tensile strength of the cotton packaging film is improved under the condition that the second cotton packaging film is not damaged. According to the cotton packaging film with high tensile strength and the machining method of the cotton packaging film, the process is simple, the practicability is high, low-temperature (20 DEG C) resistance production can be achieved, and the tensile strength and toughness of the cotton packagingfilm are greatly improved in a gluing and heat sealing dual-reinforcing manner.

Description

technical field [0001] The invention relates to the technical field of cotton baling film processing and production, in particular to a cotton baling film with high tensile strength and a processing method thereof. Background technique [0002] With the improvement of the level of agricultural mechanization, the demand for cotton baling film for cotton harvesters is increasing day by day. In the continuous production process of cotton baling film, due to the limitation of the length of the machine, it is often necessary to splice multiple films. At present, the commonly used method is the tape bonding method. Although multi-film reinforcement splicing has been realized, there are still problems such as tape reverse collection and packaging film rewinding, especially in low temperature (-20°C) environment. If it is lowered, it is easy to cause the cotton baling film to tear. For this reason, we have proposed a kind of cotton baling film with higher tensile strength and its ...
