Detailed Description

In the related art, after the low-density polyethylene resin is melted, a double-layer plastic film is manufactured in a forming die, and then the bubble film is manufactured by a bubble forming machine through bubble suction forming. In the bubble forming machine, a plastic film is formed into a bubble by vacuum forming on a vacuum roll, and the bubble is compounded with another plastic film into a whole, and the latter is tightly attached to the opening surface of the bubble to seal the bubble to form air-containing bubbles, thereby obtaining a bubble film. As shown in fig. 1 and 2, the bubble film 100 includes a base material of a plastic film and a plurality of bubbles 1301 formed by coating the base material, the plurality of bubbles 1301 are uniformly distributed on the base material, and each of the bubbles 1301 has a cylindrical shape.

In the process of transporting the product packaged by the bubble film, external energy input such as vibration, falling, impact, pressure and the like can be inevitable. When the local pressure formed by the above factors is too high, the tensile strength of the material of the bubbles may be exceeded, and the bubbles may rupture and fail, thereby causing the internal product to be directly exposed to external input energy, which may cause damage and breakage of the internal product. In the related art, a thick plastic film is added to the non-bubble surface of the bubble film, or a material with a larger thickness (such as polyethylene) is directly used to manufacture the bubble film. However, such a solution has no significant effect on reducing the failure rate of the bubble, the ability of the bubble to resist impact deformation is still poor, and the buffering ability of the bubble film is poor.

To solve the technical problem, the embodiment of the application provides an air bubble film and an air bubble bag. The bubble film includes a first substrate and a plurality of bubble groups. The plurality of bubble groups are distributed on the surface of the first base material, and each bubble group is connected with the first base material; each bubble group comprises at least two bubbles, and the adjacent outer wall surfaces of the two adjacent bubbles are connected with each other. Therefore, the characteristic that the directions of air pressure and pressure are opposite when the adjacent interconnected bubbles are subjected to external force is utilized, the opposite air pressure acting force is provided for the bubbles subjected to the external force action, so that the external force action on the bubbles is resisted, the capability of resisting impact deformation of the bubbles is enhanced, the probability of breakage and failure of the bubbles is reduced, and the buffer capacity of the bubble film and the bubble bag comprising the bubble film is improved.

Each bubble group 130 includes at least two bubbles 1301, and the outer wall surfaces of two adjacent bubbles 1301 close to each other are connected.

The material of the bubble group 130 and the first substrate 110 may include a plastic film made of a polyethylene material. Each bubble 1301 in the bubble group 130 includes a bubble wall forming a closed space and air filled inside the bubble wall. At least one bubble 1301 of the set of bubbles 130 is attached to the first substrate. That is, at least one bubble 1301 of the optional set of bubbles 130 is attached to the first substrate, and the remaining bubbles 1301 are attached to the at least one bubble 1301 attached to the first substrate 110; optionally, all of the bubbles 1301 are attached to the first substrate 110. Wherein, when the bubble 1301 is connected to the first substrate 110, the plastic film at the position where the first substrate 110 is connected to the bubble 1301 can be a part of the bubble wall of the bubble 1301.

The outer wall surfaces of two adjacent air bubbles 1301 close to each other are optionally connected by a connecting member 140, and optionally, the connecting member 140 is an adhesive. In some embodiments, adjacent bubbles 1301 may also optionally have a common sidewall to allow interconnection of the two.

According to the bubble film 100 provided by the embodiment of the application, the characteristic that the directions of air pressure and pressure are opposite when the adjacent interconnected bubbles 1301 are subjected to external force is utilized, the gas pressure acting forces with opposite directions are provided for the bubbles subjected to the external force action, so that the external force action on the bubbles is resisted, the capability of resisting impact deformation of the bubbles 1301 is enhanced, the probability of breakage and failure of the bubbles 1301 is reduced, and the buffering capacity of the bubble film 100 and a bubble bag comprising the bubble film 100 is improved.

In one possible embodiment, as shown in fig. 3-6, the first substrate 110 has a first surface 111 and a second surface 112 opposite to each other, and the plurality of bubble groups 130 are distributed on at least one of the first surface 111 and the second surface 112.

Illustratively, as shown in fig. 3-4, a plurality of bubble groups 130 are uniformly distributed only on the second surface 112 of the first substrate 110, so that the bubble film 100 can provide a single-sided protection for the interior product. As shown in fig. 5 to 6, a plurality of bubble groups 130 are distributed on both the first surface 111 and the second surface 112 of the first substrate 110, so that the bubble film 100 can provide double-sided protection to the contents.

In one possible implementation, and as shown with reference to fig. 3-10, the shape of the bubble 1301 comprises a half-cylindrical shape; alternatively, the shape of the bubble 1301 comprises a prism shape; alternatively, the shape of the bubble 1301 includes any one of a cylindrical shape and an elliptic cylindrical shape.

Illustratively, as shown in fig. 5-8, the shape of the bubble 1301 may comprise a half-cylindrical shape. As shown in fig. 3 and 4, the shape of the bubble 1301 may include a prism shape. As shown in fig. 9 and 10, the shape of the bubble 1301 may include an elliptical cylinder. In addition to this, the shape of the bubble 1301 may include a combination of any two or more of a semi-cylindrical shape, a prismatic shape, a cylindrical shape, and an elliptical cylindrical shape. In some embodiments, the shape of bubble 1301 may also include other irregular shapes.

Therefore, the shape of the bubbles with the relatively flat outer wall surface is selected, so that the connection area of the outer wall surfaces close to each other between the adjacent bubbles 1301 can be increased, the stability of the connection relation between the adjacent bubbles 1301 is improved, and the transmission of the gas pressure acting force between the adjacent bubbles is more reliable.

As an alternative embodiment, two adjacent air bubbles 1301 are semi-cylindrical, the connection surface of the concave side and the convex side of the semi-cylindrical air bubbles 1301 in the circumferential direction forms two end surfaces, and the two end surfaces of the two adjacent semi-cylindrical air bubbles 1301 are arranged opposite to each other in pairs and connected.

As shown in fig. 5 to 8, the semi-cylindrical bubble 1301 includes a concave side and a convex side, the concave side is an inner ring side of the semi-cylindrical bubble 1301, the convex side is an outer ring side of the semi-cylindrical bubble 1301, the concave sides of the two semi-cylindrical bubbles 1301 are arranged opposite to each other, two end surfaces in a circumferential direction of the semi-cylindrical bubble 1301 are arranged opposite to each other and connected by a connection member 140, and the two semi-cylindrical bubbles 1301 are surrounded to form a ring-cylindrical structure.

Thus, two outer side walls which are mutually connected are arranged between the two bubbles 1301, the positions of the bubbles 1301 for receiving the acting force of the resisting gas pressure are increased, the capacity of the bubbles 1301 for resisting impact deformation is enhanced, the damage failure probability of the bubbles 1301 is reduced, and the buffer capacity of the bubble film 100 is improved.

In one possible implementation, as shown in fig. 3-6, each bubble 1301 of the bubble group 130 is attached to the surface of the first substrate 110 by a film-coating process. The side wall surfaces of two adjacent bubbles 1301 close to each other are connected.

As shown in fig. 3 to 6, each bubble 1301 is connected to the first base material 110 by a film forming process, so that the side wall surfaces of adjacent bubbles 1301 are close to each other, and the side wall surfaces close to each other are connected by a connecting member.

Thus, the bubble 1301 is relatively simple to manufacture, and the connection relationship of the bubble 1301 on the first substrate 110 is stable and reliable. The arrangement and connection of the bubbles 1301 in the bubble film 100 are relatively simple, and the purpose of improving the cushioning ability of the bubble film 100 can be achieved.

In one possible embodiment, and as shown with reference to fig. 7-14, bubble film 100 further includes a second substrate 120, first substrate 110 and second substrate 120 being oppositely disposed, second substrate 120 including third and fourth opposing

surfaces

123, 124, second and

third surfaces

112, 123 being positioned between first and

second substrates

110, 120.

At least some of the plurality of bubble groups 130 are located on the first substrate 110, and at least some of the plurality of bubble groups 130 are located on the second substrate 120.

The second substrate 120 may be made of the same material as the first substrate 110, and includes a plastic film made of polyethylene material. The second substrate 120 is disposed opposite to the first substrate 110, a portion of the bubble group 130 is connected to the second substrate 120, and the bubble group 130 connected to the second substrate 120 is directly or indirectly connected to the first substrate 110.

In this way, by additionally providing the second substrate 120, a part of the bubble groups 130 is distributed on the second substrate 120, and the part of the bubble groups 130 is simultaneously connected to the first substrate 110, so that the capability of the bubble groups 130 against impact deformation is enhanced, the probability of failure of breakage of the bubbles 1301 is reduced, and the cushioning capability of the bubble film 100 and the bubble bag including the bubble film 100 is improved.

As an alternative embodiment, the bubble groups 130 on the second substrate 120 are distributed on at least one of the third surface 123 and the fourth surface 124.

When the bubble groups 130 on the second substrate 120 are only distributed on the third surface 123 and no bubble group 130 is distributed on the second surface 112 of the first substrate 110, the bubble groups 130 distributed on the third surface 123 can be directly connected to the second surface 112, so that the bubble groups 130 distributed on the third surface 123 are directly connected to the first substrate 110.

When the bubble groups 130 on the second substrate 120 are only distributed on the third surface 123 and the bubble groups 130 are also distributed on the second surface 112 of the first substrate 110, the bubble groups 130 distributed on the third surface 123 and the bubble groups 130 distributed on the second surface 112 can be connected to each other, so that the bubble groups 130 distributed on the third surface 123 are indirectly connected to the first substrate 110; alternatively, the bubble groups 130 distributed on the second surface 112 are connected to the first substrate 110 by a film forming process, the plastic film forming the bubble groups 130 distributed on the second surface 112 is connected to the first substrate 110, the bubble groups 130 distributed on the third surface 123 are connected to the plastic film forming the bubble groups 130 distributed on the second surface 112, and the bubble groups 130 distributed on the third surface 123 are indirectly connected to the first substrate 110.

When the bubble groups 130 on the second substrate 120 are only distributed on the fourth surface 124 and no bubble groups 130 are distributed on the second surface 112 of the first substrate 110, the third surface 123 of the second substrate 120 is directly connected to the second surface 112 of the first substrate 110, so that the bubble groups 130 distributed on the fourth surface 124 are indirectly connected to the first substrate 110 through the second substrate 120.

When the bubble groups 130 on the second substrate 120 are only distributed on the fourth surface 124 and the bubble groups 130 are distributed on the second surface 112 of the first substrate 110, the third surface 123 of the second substrate 120 is connected to the bubble groups 130 distributed on the second surface 112, so that the bubble groups 130 distributed on the fourth surface 124 are indirectly connected to the first substrate 110 through the second substrate 120.

When the bubble groups 130 on the second substrate 120 are distributed on the third surface 123 and the fourth surface 124, the connection of the bubble groups 130 on the second substrate 120 to the first substrate can be realized by referring to the way that the bubble groups 130 are only distributed on the third surface 123 of the second substrate 120.

In this way, the bubble group 130 can be arranged and connected on the first substrate 110 in various ways, and has a safety protection effect on the inner products, so that the buffering capacity of the bubble film 100 and the bubble bag comprising the bubble film 100 is improved.

In one possible embodiment, as shown in fig. 7-14, at least a portion of the bubble groups 130 are located between the first substrate 110 and the second substrate 120, each bubble group 130 located between the first substrate 110 and the second substrate 120 including a first bubble 131 and a second bubble 132, the first bubble 131 being attached to the second surface 112, and the second bubble 132 being attached to the third surface 123.

Wherein the first bubble 131 is optionally attached to the second surface 112 by a lamination process, and the second bubble 132 is optionally attached to the third surface 123 by a lamination process.

In this way, the arrangement and connection of the first bubble 131 and the second bubble 132 between the first substrate 110 and the second substrate 120 can be flexibly selected, and the first bubble 131 and the second bubble 132 mutually provide a pressure acting force against impact deformation, thereby improving the buffering capacity of the bubble film 100 and the bubble bag including the bubble film 100.

The connection of the first bubble 131 and the second bubble 132 may include the following two alternative embodiments:

in a first alternative embodiment, referring to fig. 7 to 12, in the thickness direction of the bubble film 100, the first bubbles 131 and the second bubbles 132 are arranged in a staggered manner, and the side wall surfaces of the adjacent first bubbles 131 and second bubbles 132 are connected to each other.

With this arrangement, the cushioning ability of the bubble film 100 and the bubble bag including the bubble film 100 can be improved. The side wall surfaces of the first and

second bubbles

131 and 132 adjacent to each other are connected to each other, improving the gas pressure force transmission reliability of the adjacent bubbles 1301 in the direction perpendicular to the thickness direction of the bubble film 100.

Specifically, the mutual connection of the side wall surfaces of the adjacent first bubble 131 and second bubble 132 can include the following two possible embodiments:

as a first possible embodiment, the entire side wall surface of the first bubble 131 and the entire side wall surface of the second bubble 132 are adjacent and connected to each other, the outer wall surface of the first bubble 131 on the side close to the second substrate 120 is connected to the second substrate 120, and the outer wall surface of the second bubble 132 on the side close to the first substrate 110 is connected to the first substrate 110.

Thus, the surfaces of the first and

second bubbles

131 and 132 connected to each other include the entire side wall surfaces close to each other, so that the pressure force transmission between the first and

second bubbles

131 and 132 in the direction perpendicular to the thickness direction of the bubble film 100 is more reliable; and the first bubble 131 and the second bubble 132 are connected with the first substrate 110 and the second substrate 120, and the first substrate 110 and the second substrate 120 limit the first bubble 131 and the second bubble 132 therebetween, so that the relative position relationship and the connection relationship of the first bubble 131 and the second bubble 132 are more stable, and the bubble film 100 has stronger resistance to impact deformation.

Illustratively, as shown in fig. 7 and 8, when the first bubble 131 and the second bubble 132 are both half-cylindrical, the concave side of the first bubble 131 and the concave side of the second bubble 132 are oppositely disposed, and two end surfaces of the first bubble 131 and the second bubble 132 are attached to each other in pairs and connected by the connecting member 140. Wherein the first bubble 131 is attached to the first substrate 110 by a film forming process, and the plastic film forming the first bubble 131 is attached to the first substrate 110. The second bubble 132 is attached to the second substrate 120 through a film forming process, and the plastic film forming the second bubble 132 is attached to the second substrate 120. The outer wall surfaces of the first air bubbles 131 close to the second substrate 120 are connected by the adhesive 150 to form the plastic film of the second air bubbles 132, so that the first air bubbles 131 and the second substrate 120 are connected.
