Abstract
The invention discloses a kind of production methods of PE composite package film, including outer layer, middle layer and internal layer；Outer layer is mixed in a certain ratio by LLDPE and MLLDPE, middle layer is mixed in a certain ratio by LLDPE and MLLDPE and two kinds of different HDPE of melt flow rate (MFR), and internal layer is mixed in a certain ratio by LDPE, LLDPE, MLLDPE and two kinds of different HDPE of melt flow rate (MFR).By three-layer co-extruded film blowing device by above blowing the new material to be formed, not only the stiffness of CPP had been maintained but also can be than CPP more resistant to cryogenic freezing, it carries out being compounded to form composite material with other materials, barrier property requirement can be reached, this new material can be made to reach certain stiffness requirement again, CPP is solved the problems, such as intolerant to cryogenic freezing, therefore the present invention is with a wide range of applications.
Description
Technical field
The present invention relates to technical field of composite materials, specially a kind of production method of PE composite package film and products thereof
Purposes.
Background technique
Our company finds the materials'use CPP production of flexible package, although firmly in actual production and client's later period are fed back
It spends, but in being applied to some packagings for needing cryogenic freezing product, embrittlement is easy after packaging bag cryogenic freezing, causes to wrap
Product leakage in pack.
Summary of the invention
The technical problem to be solved by the present invention is to packaging bags can both guarantee enough hardness or at low ambient temperatures
It uses.
In order to solve the above-mentioned technical problem, technical solution of the present invention is a kind of production method of PE composite package film, special
Sign is: includes the following steps,
S1: LLDPE and MLLDPE are mixed in proportion；
S2: LLDPE and MLLDPE and the first HDPE and the 2nd HDPE are mixed in proportion, wherein first HDPE is molten
Body flow rate is 1.0g/10min, and the melt flow rate (MFR) of the 2nd HDPE is 0.25g/10min；
S3: LDPE, LLDPE, MLLDPE, the first HDPE and the 2nd HDPE are mixed in proportion；
S4: being heated into stream modeling shape for the extruder that mixture in S1, S2, S3 passes through three-layer co-extruded film blowing device respectively, then
By die head blown film formed it is outer, in, the three-in-one new material of internal layer.
It is preferred: LLDPE described in step S1, the MLLDPE weight ratio be 5:1.
It is preferred: the weight ratio of LLDPE described in step S2, the MLLDPE, the first HDPE, the 2nd HDPE
For 3:1:1:1.5.
It is preferred: LDPE described in step S3, the LLDPE, the MLLDPE, the first HDPE, described second
The weight ratio of HDPE is 2:1:1:1:1.5.
New material application of the invention is in flexible package.
The stiffness that the present invention has the advantages that 1. can reach CPP compared with existing material will be gone, moreover it is possible to reach ratio
CPP can substitute existing CPP material more resistant to cryogenic freezing requirement completely；
2. the new material can be used for the packaging of cryogenic freezing material, material is avoided because of damage caused by packaging bag rupture
It loses.
Specific embodiment
To keep the present invention easier to understand, specific embodiments of the present invention are further illustrated below.
Embodiment 1
S1: LLDPE and MLLDPE are mixed according to the above ratio, and are heated to stream modeling shape；
S2: LLDPE and MLLDPE and the HDPE of two kinds of different melt flow rates are mixed according to the above ratio, and heated
Shape is moulded to stream；
S3: LDPE, LLDPE, MLLDPE and the HDPE of two kinds of different melt flow rates are mixed according to the above ratio, and
It is heated to stream modeling shape, wherein temperature is 200 degrees Celsius；
S4: the mixture of stream modeling shape in S1, S2, S3 is connect blown film with the extruder of three-layer co-extruded inflation film manufacturing machine and forms three conjunctions
First it is simple and convenient to realize prepared by material, second utilizes three layers of mixing that can guarantee in S1 for extrusion film machine for one new material
In mixture and S3 in object, S2 mixture heat-sealing it is high-efficient, heat-sealing effect it is good, avoid material from deforming, extend making for material
Use the service life.
Inspection data is as follows:
Reference standard QB/10004-2008, examining two materials is respectively PA/CPP (traditional material), PA/PE (this material
Material) packaging bag anti-seismic design, specific inspection data is as shown in the table.
Above the embodiments of the present invention are described in detail, but the present invention is not limited to described embodiments.It is right
For those skilled in the art, in the case where not departing from the principle of the invention and spirit, these embodiments are carried out more
Kind change, modification, replacement and modification, still fall in protection scope of the present invention.
