Performances easily affected by environment etc..
Utility model content
In view of the above deficiencies, the purpose of this utility model is to provide a kind of biodegradable courier bag, courier bag is realized
Degradable ability, and degradation speed is very fast, waterproof performance is good, good toughness.
Used technical solution is the utility model in order to achieve the above objectives:
A kind of biodegrade courier bag, the lower film including upper film and upper film heat sealing, the upper film or lower film are from outside to inside
Including PBAT plastic layer, PLA plastic layer and LDPE plastic layer.
The upper film or lower film further include being set to innermost froth bed as a further improvement of the utility model,.
The material of the upper froth bed or lower froth bed is LDPE plastics as a further improvement of the utility model,.
The upper film length is less than lower film length as a further improvement of the utility model, and the lower film protrudes from
It is provided with viscose top on the inside of membrane part, is provided with release paper on viscose top.
It is additionally provided with a bending part between the upper film and lower film as a further improvement of the utility model, the bending
Portion is that a bar plastic film is folded to form, and its left end and right end heat-sealing are together between upper film and lower film.
It further includes the overlay being set on the outside of film as a further improvement of the utility model, this is transparent
Plastic foil is rectangle, four in three while with upper film heat sealing.
It further includes the chance water discoloration adhesive sticker being set on the outside of film as a further improvement of the utility model,.
The utility model has the following beneficial effects:
(1) the courier bag film compound by a variety of degradation plastics, is improved as far as possible while providing degradability
Degradable speed improves the courier bag feature of environmental protection, and outermost PBAT layers of toughness, heat-resisting, impact resistance is good, protects content not
By external environment influence, PLA layers are made using renewable plant resources, and environmental-protecting performance is more preferable, and LDPE layer has light-biology drop
Performance is solved, can first be ruptured under ultraviolet light irradiation condition, composite degradation factor improves the degradation speed of courier bag, is simultaneously
When avoiding courier bag routine use, performance is affected, and by the layer, it closes inside, it is ensured that routine use can not be by illumination；
(2) by setting bending part, increase the volume of courier bag, while the left and right ends of bending part are hot together with upper lower film
Sealing, neat it is not necessary that courier bag can also be kept to stack when strutting courier bag.
Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and specific embodiment, to the utility model
It is described further.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is film or lower membrane structure diagram on the utility model；
Fig. 3 is the utility model centre section schematic diagram.
In figure, upper film 1, lower film 2, PBAT plastic layer 3, PLA plastic layer 4, LDPE plastic layer 5, froth bed 6, viscose top 7,
Bending part 8, overlay 9 meet water discoloration adhesive sticker 10.
Specific embodiment
Further to illustrate that the utility model is the technical means and efficacy for reaching predetermined purpose and being taken, below in conjunction with
Specific embodiment of the present utility model is described in detail in attached drawing and preferred embodiment.
Fig. 1 and Fig. 2 are please referred to, the present embodiment provides a kind of biodegradable courier bags, including upper film 1 and upper 1 heat sealing of film
Lower film 2, the upper film 1 or lower film 2 include PBAT plastic layer 3, PLA plastic layer 4 and LDPE plastic layer 5 from outside to inside.It is logical
The compound courier bag film of a variety of degradation plastics is crossed, degradable speed is improved as far as possible while degradability is provided, mentions
The high courier bag feature of environmental protection, outermost PBAT layers of toughness, heat-resisting, impact resistance is good, protects content not by external environment
It influences, PLA layers are made using renewable plant resources, and environmental-protecting performance is more preferable, and LDPE layer has optically and biologically degrading performance, in purple
It can first be ruptured under outside line irradiation condition, composite degradation factor improves the degradation speed of courier bag, while to avoid courier bag
When routine use, performance is affected, and by the layer, it closes inside, it is ensured that routine use can not be by illumination.
The upper film 1 or lower film 2 further include being set to innermost froth bed as a further improvement of the utility model,
