Abstract
The invention discloses an aluminum-plastic sealing film for a biodegradable packaging bottle. The aluminum-plastic sealing film comprises a PLA transparent layer, a printing layer, an adhesive film layer, a blocking layer, an adhesive film layer and an adhesive layer which are sequentially arranged from top to bottom; the adhesive film layer and the bonding layer are both biodegradable materials; the barrier layer is an aluminum foil; the printing layer is environment-friendly ink. The aluminum-plastic sealing film disclosed by the invention is good in sealing effect after being subjected to electromagnetic induction heating sealing, meanwhile, is biodegradable, and is green and environment-friendly.
Description
Technical Field
The invention belongs to the technical field of biodegradable packaging, and particularly relates to an aluminum-plastic sealing film for a biodegradable packaging bottle.
Background
In the aspect of packaging bottles, the main materials at present are polyethylene, polypropylene, polyethylene terephthalate (PET), etc., these traditional petroleum-based plastic materials are difficult to degrade in natural environment, and bring serious pollution problems to the natural environment after being discarded, along with the increasing importance of the country on the plastic pollution problem, a series of relevant laws and regulations for solving white plastic pollution are provided, one direction is to actively develop biodegradable materials, such as polylactic acid (PLA), polyhydroxyalkanoate (PHA), polybutylene adipate/terephthalate (PBAT), polybutylene succinate (PBS), polycaprolactone (PCL), polytrimethylene carbonate (PPC), etc., so that the development and application of the degradable materials are rapidly developed.
The polylactic acid (PLA) raw material is prepared by fermenting corn, cassava, straw and other bio-based materials, and can be degraded into CO by microorganisms 2 And H 2 O, is environment-friendly and does not produce plastic pollution. PLA materials are also gradually used in the aspect of biological packaging bottles, and the problem of poor water vapor barrier property of the PLA is solved by blending the PLA with other materials.
When the biodegradable packaging bottle is applied to packaging food, medicines and cosmetics, an electromagnetic induction sealing composite film is needed and at least comprises a hot melting bonding layer and an aluminum foil layer. The electromagnetic induction sealing film is extruded at the mouth of the container to be sealed, under the action of a high-frequency electromagnetic field, the aluminum foil produces huge eddy current to rapidly generate heat, and the bonding film layer on the lower layer of the melting aluminum foil is connected with the mouth of the container in close contact, so that the purpose of non-contact air-tight sealing is achieved.
The conventional sealing film structure for Polyethylene (PE) bottle includes PET layer/printing layer/adhesive layer/PE layer/adhesive layer/aluminum layer/adhesive layer/PE adhesive layer, for example, patent CN213830758U, CN109291570A, etc. Due to PE bonding of conventional sealing filmsThe layer is not the same material with the material of biodegradable packing bottle, and electromagnetic induction can't make the two hot melt adhesion, so the electromagnetic induction that traditional sealing film can't be used for biodegradable packing bottle seals the requirement, need develop a neotype sealing film that matches with biodegradable packing bottle material to the used plastics material of sealing film all is biodegradable material, abandons back plastics part can be decomposed into CO by the microorganism in the environment partly 2 And H 2 And O, the damage to the environment is minimized, and the problem of environmental pollution caused by nondegradable plastic materials after the traditional sealing film is discarded is solved.
Disclosure of Invention
Aiming at the defects that the biodegradable packaging bottle is incompatible with the traditional sealing film material and cannot be welded, and the traditional sealing film material is not degraded, the invention provides an aluminum-plastic sealing film for the biodegradable packaging bottle, which is provided by the invention, and has good sealing effect after being sealed by electromagnetic induction heating and is biodegradable.
The purpose of the invention is realized by the following technical scheme:
an aluminum-plastic sealing film for a biodegradable packaging bottle comprises a PLA transparent layer, a printing layer, an adhesive film layer, a blocking layer, an adhesive film layer and an adhesive layer which are sequentially arranged from top to bottom; the adhesive film layer and the bonding layer are both made of biodegradable materials; the barrier layer is an aluminum foil; the printing layer is environment-friendly ink; the aluminum-plastic sealing film is formed by hot-pressing and compounding.
Further, the PLA transparent layer comprises the following components in percentage by mass: 83.5-95.5% of PLLA (poly-L-lactic acid), 0-10% of PDLA (poly-D-lactic acid), 0.1-10% of PBS (poly-butylene succinate), 0.1-0.5% of nucleating agent, 0.1-0.5% of lubricant, 0.05-0.2% of antioxidant and 0.2% of opening agent.
