Embodiment 1

[0022] The preparation process of a PET-PVDC-PE liquid pharmaceutical composite packaging film described in the present invention comprises the following steps: comprising the following steps:

[0023] Step 1: The PET film is discharged from the unwinding machine, and after corona treatment, a primer of 0.8-1.2 gsm is applied on the surface of the PET film, and the first drying is performed at 30-50 °C;

[0024] Step 2: apply PVDC emulsion 20gsm for the first time on the PET film after the first drying, and dry for the second time at 30-50 °C;

[0025] Step 3: coating PVDC emulsion 20gsm for the second time on the PET film after the second drying, and drying at 30-50 °C for the third time;

[0026] Step 4: A layer of PE film is attached on both sides of the PET-PVDC composite film obtained in step 3;

[0027] Step 5: Fold the PET-PVDC-PE film obtained in Step 4 on both sides into the shape of a medicinal packaging bottle.

[0028] Wherein: the step 5 specifically includes th...

Abstract

The invention discloses a preparation technology of a composite packaging film for PET-PVDC-PE liquid medicine. The technology comprises the following steps that 1, a PET film is discharged through an unwinding machine and then subjected to corona treatment, the surface of the PET film is coated with 0.8-1.2 gsm of base glue, and first drying is conducted at 30 DEG C to 50 DEG C; 2, 20 gsm of PVDC emulsion is applied for the first time on the PET film which is dried for the first time, and second drying is conducted at 30 DEG C to 50 DEG C; 3, 20 gsm of PVDC emulsion is applied for the second time on the PET film which is dried for the second time, and third drying is conducted at 30 DEG C to 50 DEG C; 4, PE films are attached to the two surfaces of the PET-PVDC composite film obtained in the third step respectively; 5, the two surfaces of the PET-PVDC-PE film obtained in the fourth step are folded into the shape of a packaging bottle for medicine. The preparation technology is easy to operate, the obtained composite packaging film for the liquid medicine does not change along with changes of humidity, and the quality of products is not affected.

Description

technical field [0001] The invention relates to a medicinal packaging material, in particular to a preparation process of a PET-PVDC-PE liquid medicinal composite packaging film. Background technique [0002] The traditional printing and packaging industry usually adopts a multi-layer composite packaging structure with solvents for drug packaging bags, which is expensive and has the characteristics of volatile solutes, low environmental protection, and poor aesthetics; in addition, for medicines, especially liquid medicines The multi-layer composite packaging often requires environmental protection, high transparency, and strong moisture resistance. [0003] The materials used in the existing packaging bags for packaging liquid medicines have weak moisture resistance, which affects the quality of liquid medicines and is not environmentally friendly. [0004] Based on this, a preparation process of PET--PVDC-PE liquid pharmaceutical composite packaging film was researched an...
