Embodiment 1

[0016] Embodiment 1: (by mass)

[0017] The formula of PE heavy packaging film material composition is:

[0018] Linear Low Density Polyethylene: 70%,

[0019] (Select the product whose comonomer is octene)

[0020] LDPE: 10%,

[0021] (Select LDPE165 from Exxon, USA)

[0022] Metallocene linear low density polyethylene: 16%,

[0023] (Choose 1018CA from Exxon, USA)

[0024] Anti-blocking agent, slip agent, antistatic agent, antioxidant, processing and heat stabilizer: According to a certain proportion, the total accounts for 4%.

[0025] After the three-layer co-extrusion blown film production line is extruded according to the production process, the performance of the product is sampled and analyzed. The mechanical properties of the obtained product all meet the standards, and compared with other heavy packaging products, the puncture resistance and film strength are significantly improved. . The specific data are as follows:

[0026]

Embodiment 2

[0027] Embodiment 2 (by weight)

[0028] Linear Low Density Polyethylene: 80%,

[0029] (Select the comonomer as the product of hexene),

[0030] LDPE: 6%,

[0031] (Select LDPE165M from Beijing Yanhua Company),

[0032] Metallocene linear low density polyethylene: 10%

[0033] (Choose 1018CA from Exxon, USA)

[0034] Anti-blocking agent, slip agent, antistatic agent, antioxidant, processing and heat stabilizer: According to a certain proportion, the total accounts for 4%.

Embodiment 3

[0035] Embodiment 3 (by mass)

[0036] Linear Low Density Polyethylene: 60%,

[0037] (select the comonomer to be the product of octene),

Abstract

A polyethylene heavy packaging film composite can be widely used for producing blisterpack, such as FFS package, large goods package, tray package and so on, which can effectively improve the all round performance of packaging film, and make the package of goods more beauty, firm, green and effective. The film composite comprises: linear low density polyethylene accounting for 60-80% of the sum of the material, low density polyethylene accounting for 5-25% of the sum of the material, metallocene linear low density polyethylene accounting for 10-30% of the sum of the material, additive accounting for 3-7% of the sum of the material. An automatic feed proportioning system feeds the material of three extruders to die head and the heavy packaging film combination is obtained after three-layer extruding and mixing. The additive is combination of one or several kinds of slippery agent, antistatic agent, antioxidant, opening agent, thermal stabilizer.

Description

technical field [0001] The invention relates to a polyethylene (PE) heavy packaging film material composition. The invention belongs to the technical field of plastic processing application. Background technique [0002] Heavy-duty packaging film is a new type of packaging material developed in China in recent years. It is a new type of packaging film product that can realize multiple processes and operations such as continuous one-time automatic forming, opening filling, heating and sealing. It can meet the needs of high-speed filling, large-scale storage and transportation and automatic palletizing of large-scale production automatic packaging lines. It not only greatly improves the packaging efficiency, but also simplifies the bag making process. It only needs co-extrusion blow molding, (online or offline) printing, sealing and cutting Bag making, greatly reducing the overall packaging cost. Traditional composite woven bag packaging must go through a series of complex p...
