Embodiment 1
[0031] A modified film used for the packaging of alcoholic beverages, which consists of the following components in weight percentage:
[0032]
[0033] The lubricant is one or a mixture of two or more of oxidized polyethylene wax, homopolymer lubricant or fatty acid complex grease.
[0034] Described a kind of modified film preparation method for packaging of alcoholic beverages comprises the following steps:
[0035] Step 1. Production of finished powder
[0036] 1) Put the polyvinyl chloride resin powder into a high-speed mixer with cold mixing and stir, and the polyvinyl chloride resin powder generates heat by friction during the stirring process;
[0037] 2) Add stabilizer (methyl tin heat stabilizer), lubricant and plasticizer (DOP) at 60°C;
[0038] 3) Add enhancer (MBS), processing aid (ACR) and aluminum powder at 110°C;
[0039] 4) Finish mixing at 125°C, put it into a cold mixing pot for forced cooling;
[0040] Step 2, film production
[0041] 1) Put the coo...
Embodiment 2
[0047] A modified film used for the packaging of alcoholic beverages, the formula components are the same as those in Example 1.
[0048] Described a kind of modified film preparation method for packaging of alcoholic beverages comprises the following steps:
[0049] Step 1. Production of finished powder
[0050] 1) Put the polyvinyl chloride resin powder into a high-speed mixer with cold mixing and stir, and the polyvinyl chloride resin powder generates heat by friction during the stirring process;
[0051] 2) Add stabilizer (methyl tin heat stabilizer), lubricant and plasticizer (DOP) at 65°C;
[0052] 3) Dosing enhancer (MBS), processing aid (ACR) and aluminum powder at 90°C;
[0053] 4) Finish mixing at 125°C, put it into a cold mixing pot for forced cooling;
[0054] Step 2, film production
[0055] 1) Put the cooled finished product powder obtained in step 1 into the screw of the calendering tablet machine for melting. The screw is a planetary screw, and the screw pa...
Embodiment 3
[0061] A modified film used for the packaging of alcoholic beverages, the formula components are the same as those in Example 1.
[0062] Described a kind of modified film preparation method for packaging of alcoholic beverages comprises the following steps:
[0063] Step 1. Production of finished powder
[0064] 1) Put the polyvinyl chloride resin powder into a high-speed mixer with cold mixing and stir, and the polyvinyl chloride resin powder generates heat by friction during the stirring process;
[0065] 2) Add stabilizer (methyl tin heat stabilizer), lubricant and plasticizer (DOP) at 70°C;
[0066] 3) Add enhancer (MBS), processing aid (ACR) and aluminum powder at 100°C;
[0067] 4) Finish mixing at 125°C, put it into a cold mixing pot for forced cooling;
[0068] Step 2. Film production
[0069] 1) Put the cooled finished product powder obtained in step 1 into the screw of the calendering tablet machine for melting. The screw is a planetary screw, and the screw part i...
