Postopek izdelave fleksibilne embalaže iz aluminijaste folije

The production process of flexible packaging aluminum foil usually includes the following key links: blank material selection, aluminum foil rolling, rezanje, cleaning and disinfection, itd.

Below we will introduce the specific steps and key points in these links in detail.

Izbira surovin

The raw materials (blanks) for producing aluminum foil are mainly divided into cast-rolled blanks and hot-rolled blanks. Compared with hot-rolled blanks, the quality of cast-rolled blanks is more difficult to control. Since the deformation of aluminum foil rolled with cast-rolled billets is much smaller, the quality of cast-rolled billets, such as air passages, vključki, segregation, coarse grains and other defects, have a more direct impact on aluminum foil rolling. The following figure shows different blanks. Raven kristalne slike materiala.

Postopek valjanja

Glavna oprema za valjanje aluminijaste folije vključuje: groba valjarna, vmesna valjarna, navijalec, in končni mlin; razvijalniki, škarje, žarilne peči, itd. v nadaljnjih procesih; in brusi za redno obdelavo in vzdrževanje tlačnih valjev. Obstaja tudi oprema, ki jo vsak proizvajalec prilagodi glede na sorte izdelkov in specifikacije, ki jih proizvaja.

Postopek izdelave fleksibilne embalaže iz aluminijaste folije

Proizvodni postopek kalandriranja aluminijaste folije:

Aluminijasta folija groba, srednje in končne valjarne se v glavnem delijo glede na obseg debeline izdelka, in njihovi ustrezni načini krmiljenja so različni.

Grobo valjanje: minimalna izhodna debelina: 0.02~0,04 mm, v glavnem temelji na nadzoru položaja vrzeli in nadzoru po napetosti;

Vmesno valjanje: minimalna izhodna debelina: 0.01mm, z nadzorom napetosti kot glavnim poudarkom;

Finish rolling: minimalna izhodna debelina: 0.004.4*2mm, mainly controlled by speed and post-tension;

Rezanje: According to the needs, the fine-rolled double aluminum foil is slit into finished aluminum coils of different diameters and widths, generally divided into 3-inch and 6-inch inner diameters;

Quenching: Na splošno, an electric-heated positive pressure or negative pressure annealing furnace is used, and different annealing temperatures and times are set as needed to recrystallize the aluminum foil to achieve the purpose of removing oil and re-establishing performance.

Rezanje

The rolled aluminum foil is usually larger, which is not conducive to packaging and use. Zato, slitting is required during the production process. Slitting is the use of professional equipment to cut large pieces of aluminum foil into small pieces of various sizes according to requirements. Precision and efficiency must be paid attention to during the slitting process to ensure the smooth progress of the subsequent production process.

Klasifikacija aluminijaste folije za fleksibilno embalažo

Flexible packaging aluminum foil mainly uses the metallic luster, svetlobna pregrada, air barrier and certain strength and ductility of aluminum foil. Glede na različne uporabe, the emphasized performance is also different. Aluminum foil for flexible packaging can be divided into three categories according to the use:

The first category, food and drug packaging, is mainly sealed, mainly emphasizing gas barrier properties, light barrier properties, and non-toxicity. This kind of aluminum foil includes: packaging of medicines and quasi-drugs (medicinske opreme, medical supplies), 0.02MM, 0.015MM, 0.009MM, 0.007MM.

Več težav s fleksibilno embalažno aluminijasto folijo

Pri fleksibilni embalažni aluminijasti foliji je trenutno treba rešiti več težav.

● Enakomernost površinskega stanja fleksibilne embalažne aluminijaste folije je predraga. If a good surface is required, the production cost will increase significantly. So far, there is no good solution.

● As a product of extreme thickness, aluminum foil almost exhausts all its plasticity. The reworkability of flexible packaging aluminum foil is not high, despite the use of new alloys and processes, (eg: 8011, 8079). There is still no good way to significantly improve plasticity. Vendar, the method of flexible packaging compound bag-making processing has less consideration for this aspect, so that bursting often occurs.

● The index for measuring the plasticity of aluminum foil is unscientific and cannot truly express the plasticity of aluminum foil. The performance of flexible packaging aluminum foil is still in the trial stage. Without scientific indicator measurement, production inspection cannot be carried out.

● Znanstvena izbira debeline, razumno kompozitno tehnologijo, in podporni materiali so tako pomembni kot zmogljivost same aluminijaste folije. Razumno ujemanje lahko ne samo stabilizira kakovost izdelka, ampak tudi zmanjša stroške.
