As described above, the present invention provides a highly anti-adhesive antibacterial film composition, a highly anti-adhesive antibacterial film material containing the same, and a method for manufacturing the same, wherein calcined shell powder is added to a polyethylene copolymer, thereby effectively improving the anti-adhesive property and antibacterial property of the highly anti-adhesive antibacterial film material made of the highly anti-adhesive antibacterial film composition, and the highly anti-adhesive antibacterial film material can be applied to various packaging materials.
The above-mentioned "high anti-sticking antibacterial film composition" may include, but is not limited to, 100 parts by weight of the polyethylene copolymer, 3.0 parts by weight to 7.0 parts by weight of the calcined shell powder, and 0.1 parts by weight to 0.2 parts by weight of the additive, but does not include the anti-sticking agent.
In the above embodiments, the polyethylene copolymer may comprise Linear Low Density Polyethylene (LLDPE). The density of the above polyethylene copolymer may be, for example, 0.90g/cm3To 0.96g/cm3. In one embodiment, the polyethylene copolymer may have a Melt Index (MI) of 2.16, for example, from 0.03g/10 min to 4.0g/10 min. It is noted that if the density and MI 2.16 of the polyethylene copolymer used do not meet the above specifications, the strength, processability and heat sealability of the high tack resistant antibacterial film material thus produced are less desirable. In one embodiment, the polyethylene copolymer may be obtained by copolymerizing ethylene and an olefin monomer having more than three carbon atoms, wherein the olefin monomer may be selected from the group consisting of butene, hexene, octene, and any combination thereof, and specifically may be an ethylene-butene copolymer, an ethylene-butene-hexene terpolymer, an ethylene-octene copolymer, and the like, such as: taisax type 3220, the present invention is not limited thereto.
In the above embodiments, the calcined shell powder may be derived from shell bodies of single-shell and/or double-shell shells, wherein the shell species of the single-shell and/or double-shell shells are not particularly limited, and may be selected from the group consisting of oyster, clam, jiu hole, malachite, mussel, abalone, pearl shell, butterfly shell, and scallop.
The shellfish meat of the above shellfish species is one of popular food materials in all over the world, but its shells cannot be eaten, and become solid waste which is not easy to handle, wherein for oyster alone, taiwan in china can produce 17 ten thousand tons of oyster shells per year on average. These shells are easily accumulated in public water areas and/or on land, causing serious odor problems, and easily causing the growth of bacteria, thereby affecting environmental sanitation. The invention selects the shell body of the single shell and/or the shell body of the double shell, and the calcined shell powder obtained after processing has antibacterial property.
The processing may include pre-treating the shell and calcining to produce calcined shell powder. In the above embodiments, the pretreatment step may be, for example, removing the residual shellfish meat on the shell, and performing surface cleaning and coarse crushing to obtain shell powder, which is well known in the art and will not be described herein.
In some embodiments, after the pre-treatment step, the shell powder may be optionally subjected to an alkali coating step to obtain an alkali-coated powder. In some embodiments, the alkali coating step coats the shell powder with a calcium salt slurry comprising at least 2.5 wt.% calcium salt, for example comprising 2.5 to 20.0 wt.% calcium salt, for 2 to 4 hours, and the weight to volume ratio (g/mL) of the shell powder to the calcium salt slurry is 0.1 to 1. In some embodiments, the calcium salt is calcium hydroxide.
In some embodiments, the aforementioned calcining step may be performed on the shell powder or the alkali-coated powder, for example, at a temperature of about 900 ℃ to 1200 ℃, to obtain a calcined shell powder. In some embodiments, the calcination time may be, for example, 3 hours to 6 hours. In some embodiments, the calcination step may be optionally followed by a grinding step, such that the particle size of the calcined shell powder can be, for example, at most 40 μm, preferably 3 μm to 10 μm, and more preferably 5 μm to 10 μm, in order to produce a film with a thickness of 40 μm or less and maintain desirable optical properties (e.g., transparency).
In some embodiments, the calcined shell powder prepared by the above steps has a core-shell structure, the core layer of the core-shell structure is micron-sized calcium oxide particles, the shell layer of the core-shell structure is nano-sized to sub-micron-sized calcium oxide particles, the average particle size of the micron-sized calcium oxide particles is 7 μm to 500 μm, and the average particle size of the nano-sized to sub-micron-sized calcium oxide particles is not greater than 200 nm. In some embodiments, the whiteness of the calcined shell powder is at least 60. The whiteness is for example 60 to 88. In some embodiments, the calcined shell powder has a zinc content of less than 1.67ppm, a manganese content of less than 40ppm, and an iron content of less than 350 ppm. In some embodiments, the shell layer of the core-shell structure is a discontinuous layer or a continuous layerAnd (3) a layer. In some embodiments, the nano-to submicron-sized calcium oxide particles have an average particle size of 60nm to 150 nm. In some embodiments, the calcined shell powder has a specific surface area of at least 8000cm2/g。
The calcined shell powder is added into the high anti-adhesion antibacterial film composition, so that the anti-adhesion property of the high anti-adhesion antibacterial film material can be endowed, the addition of the existing anti-adhesion agent can be eliminated, and the risk of the existing film material product on the human health is further reduced. In addition, the addition of the calcined shell powder can also improve the puncture resistance and antibacterial property of the anti-adhesion antibacterial film material.
It is noted that, if the content of the calcined shell powder in the high anti-sticking antibacterial film composition is less than 3.0 parts by weight, the anti-sticking property, antibacterial property and puncture resistance of the prepared high anti-sticking antibacterial film material are not ideal. If the content of the calcined shell powder in the high anti-sticking antibacterial film composition exceeds 7.0 parts by weight, the manufacturing cost is increased, the sticking resistance, the antibacterial property and the puncture resistance are not obviously improved, and the problem of the reduction of the transparency of the high anti-sticking antibacterial film material is also caused.
The additive can be, for example, a stabilizer, a plasticizer, a lubricant, a flame retardant, a colorant, a filler, an antistatic agent, an antioxidant, an acid generator and/or a foaming agent, so as to prevent the highly anti-sticky antibacterial film material made of the highly anti-sticky antibacterial film composition from being degraded by factors such as acid, alkali, temperature, ultraviolet ray, oxygen and the like, thereby prolonging the service life of the highly anti-sticky antibacterial film material. The above additives can be used in various existing products, which are well known to those skilled in the art and will not be described in detail. It is noted that, in order to achieve the effects of the additive and the manufacturing cost, the content of the additive is 0.1 to 0.2 parts by weight.
In one embodiment, the additive can be, for example, an antioxidant and an antacid, wherein the additive can comprise 40 wt% to 50 wt% of the antioxidant and 50 wt% to 60 wt% of the antacid, based on 100 wt% of the additive, wherein the antioxidant can be selected from the group consisting of hindered phenol compounds, phosphite compounds, thio-compound compounds, inorganic compounds, and any combination thereof, and specifically can be an antioxidant comprising n-octadecyl 3- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate and phenyl 3- (2, 4-di-tert-butyl) phosphite. In the above examples, the antacid may be selected from the group consisting of calcium stearate, zinc oxide, hydrotalcite, and any combination thereof, and specifically may be calcium stearate.
In one embodiment, the highly anti-sticky antibacterial film composition can be used to prepare a highly anti-sticky antibacterial film material by using the existing process. In brief, the above-mentioned high anti-sticking antibacterial film composition is provided first. Then, a mixing process was performed at room temperature for 30 minutes, and a granulation process was performed to obtain master batches. In the above examples, the granulation process can be carried out by a conventional method, for example, kneading and dispersing by a commercially available single-screw or twin-screw kneader. Taking a twin-screw mixer as an example, the granulation process may be performed at a processing temperature of 170 ℃ to 210 ℃, wherein the ratio (L/D) of the effective length of the screw to the diameter of the screw is 26 to 30, the rotation speed of the screw may be, for example, 100rpm to 200rpm, and the extrusion amount may be, for example, 5kg/h to 10kg/h, but the present invention is not limited thereto.
Then, a film blowing process is performed to obtain the highly anti-sticking antibacterial film material, wherein the thickness of the highly anti-sticking antibacterial film material can be, for example, less than or equal to 40 μm. Methods of blown film processes are well known to those skilled in the art and are therefore not described in detail.
The above-mentioned "anti-tackiness" means a property that the interfacial openness is small, wherein the openness can be evaluated by the adhesion strength of the separate-phase-pasted film in "units: gram force (gf) ". Generally, the adhesive strength of less than 30 gram force (gf) can satisfy the demand of the market for the opening property of the film material, and the opening property of the high anti-sticking antibacterial film material prepared from the high anti-sticking antibacterial film composition can be less than 10gf, which means that the high anti-sticking antibacterial film material with better anti-sticking property can be obtained without adding the existing anti-sticking agent.
The "antibacterial property" indicates the ability to inhibit the proliferation of bacteria, and can be evaluated by the antibacterial rate obtained by the thin film adhesion method described in CNS 15823, and the "high antibacterial property" indicates an antibacterial rate of more than 95.0%. Experiments prove that compared with the film material without calcined shell powder, the high-anti-adhesion antibacterial film material prepared from the high-anti-adhesion antibacterial film composition containing calcined shell powder can really and effectively inhibit the growth and/or proliferation of pathogenic bacteria such as escherichia coli and/or staphylococcus aureus.
In particular, the highly anti-tack antibacterial film material has puncture resistance in addition to high anti-tack property and antibacterial property. The "puncture resistance" is a property of resisting puncture by a foreign object and is generally expressed by "puncture strength (newton, N)". Compared with the existing film material without calcined shell powder, the high anti-sticking antibacterial film material prepared by the high anti-sticking antibacterial film composition containing calcined shell powder has better puncture resistance.
The high anti-sticking antibacterial film composition has the advantages that calcined shell powder is added into polyethylene copolymer, and the prepared high anti-sticking antibacterial film material has high anti-sticking property, high antibacterial property and high puncture resistance, and can be applied to packaging materials. It is added that the rupture strength of the high anti-adhesion antibacterial film material is slightly reduced, and the high anti-adhesion antibacterial film material is likely to be decomposed by organisms and has potential to be used as an environment-friendly material.
The present invention is described in detail by way of examples, which are not intended to limit the scope of the invention, and various modifications and alterations may be made by those skilled in the art without departing from the spirit and scope of the invention.
Example one preparation of calcined Shell powder
First, the oyster shell waste was subjected to meat residue removal and surface cleaning, and then coarsely pulverized into shell powder (average particle size about 35 mesh) by a commercially available pulverizing apparatus. Then, a calcination step was performed at a temperature of 1000 ℃ to obtain calcined shell powder. Then, a grinding step is performed so that the particle size of the calcined shell powder is 5 to 10 μm.
EXAMPLE two preparation of highly anti-sticking antibacterial film Material
Example 1
The polyethylene copolymer, the calcined shell powder of example one, the antacid, and the antioxidant were mixed at room temperature for 30 minutes according to table 1. The polyethylene copolymer is a tai-plastene 3220 available from taiwan plastic industries, ltd. The talbexatene 3220 is a copolymer of ethylene and butene, with a butene content of 8 wt% based on the talbexatene 3220. The polyethylene copolymer had a density of 0.9190g/cm3And MI 2.16 is 2.0.

Examples 2 to 5 and comparative examples 1 to 2
The film materials of examples 2 to 5 and comparative examples 1 to 2 were prepared by the same process as the film material of example 1, the polyethylene copolymers of examples 2 to 3 and comparative examples 1 to 2 were the same as example 1 except that the calcined shell powder of examples 2 to 3 and comparative examples 1 to 2 were used in different amounts, and the polyethylene copolymers of examples 4 to 5 were copolymers of ethylene and hexene in which the hexene content was 8 wt% based on the polyethylene copolymer, and 100 wt%.
Comparative example 3
The film material of comparative example 3 was prepared using the same process as the film material of example 1, wherein the polyethylene copolymer of comparative example 3 was the same as example 1, except that the composition of the film material of comparative example 3 contained the anti-adherent silica but did not contain calcined shell powder.
[ Table 1]
Example III evaluation mode
The film materials of examples 1 to 5 and comparative examples 1 to 3 were evaluated for tack resistance, antibacterial property, puncture resistance, and breaking strength as follows.
1. Anti-sticking property
The evaluation of the anti-tack property is the evaluation of the opening property by the adhesion strength measured by the method described in ASTM D3354 set forth in the American Society for Testing and Materials (ASTM). Briefly, this method separates two identical test films (film materials of comparative examples 1 to 3 or examples 1 to 5, 100 cm) that are completely bonded by testing2) The required tack strength is evaluated for openness, where a greater tack strength indicates greater openness and poorer tack resistance.
2. Antibacterial property
The evaluation of the antibacterial properties of the surface of the thin film material was carried out according to the method described in CNS 15823. First, the film materials of comparative examples 1 to 3 and examples 1 to 5 were cut into test pieces of 5cm × 5cm, and washed with 70 vol% ethanol, wherein the film material of comparative example 1 had 6 test pieces, and the film materials of comparative examples 2 to 3 and examples 1 to 5 had 3 test pieces, respectively.
Then, lyophilized bacteria of Staphylococcus aureus (Staphylococcus aureus) and Escherichia coli (Escherichia coli) registered in registers BCRC 10451 and BCRC 11634 were purchased from the Center for biological resource preservation and Research, BCRC, food road 331, new bamboo city, respectively, and subcultured 2 times using a slant medium containing 5.0g of meat essence, 10.0g of peptone, 5.0g of sodium chloride, and 15.0g of agar powder per liter, to obtain activated bacteria, and each subculture was performed at 35 ℃ for 16 to 24 hours.
Then, the suspension culture medium (culture medium containing 3.0g of meat extract, 10.0g of peptone and 5.0g of sodium chloride per liter diluted 500-fold of the original volume) and activated cells were used to prepare a suspension culture medium having a concentration of about 6X 10/ml5Bacterial suspension of individual cells. Then, the bacterial suspension was inoculated onto each of the above test pieces, and a low-density ethylene-adhesive film (4 cm. times.4 cm) was placed on the bacterial suspension. It should be noted that care should be taken not to allow the bacteria solution to overflow the film when the cover is closed. Then, the number of bacteria in the bacterial liquid was counted for 3 out of 6 sheets of the film material in comparative example 1 (no culture), while the number of bacteria was counted for 3 other 3 sheets of the film material in comparative example 1, 3 sheets of the film materials in comparative examples 2 to 3, and 1 to 5 after culturing at 35 ℃ for 24 hours. Next, the bacteriostatic rate was calculated using formula (I).
R％＝[(Ut-U0)-(At-U0)]/％ (I)
Wherein R% represents the bacteriostatic rate, U0The logarithm of the number of bacteria of the non-cultured bacterial liquid on the test piece of the film material of comparative example 1, UtThe logarithm of the number of bacteria of the cultured bacterial suspension on the test piece of the film material of comparative example 1, AtThe logarithm of the number of bacteria of the bacterial suspension cultured on the test piece of the film material of comparative examples 2 to 3 or examples 1 to 5 is shown.
3. Puncture resistance
The puncture resistance was evaluated using ASTM F1306, established by the American society for testing and materials, which, briefly, fixes the film material on a lancet holder and then applies biaxial stress to the film material at room temperature at a single test speed until a puncture hole occurred. The puncture needle seat is provided with the load cell capable of sensing the stress, so that the puncture resistance can be evaluated by the maximum stress value sensed by the load cell in the puncture process, wherein the larger the maximum stress value is, the smaller the puncture resistance is.
4. Breaking strength
The breaking strength and puncture resistance were evaluated by a tensile tester. First, the film material was fixed to a tensile tester. Then, a tensile tester is used for exerting tensile force on the film material at a tensile rate of 1mm to 500mm per minute until the film material is broken. The tensile force applied by the tensile tester at the time of breaking the film material divided by the cross-sectional area of the film material was recorded as the breaking strength of the film material in table 2.
[ Table 2]
As shown in Table 2, the film materials (examples 1 to 5) containing calcined shell powder in an amount of 3.0 parts by weight or more had an openness of less than 10 gf. In contrast, the film material of comparative example 1 had an opening property of 42.84gf, which was 6 to 10 times or more as large as that of examples 1 to 5. Secondly, the film material (comparative example 3) with silica added as an anti-sticking agent has a smaller opening than the film material (comparative example 2) containing the calcined shell powder in the same proportion, showing that the calcined shell powder can make the film material have better anti-sticking property compared with the existing anti-sticking agent. However, the film material (comparative example 2) in which the addition amount of calcined shell powder was insufficient had an opening property of more than 10gf, indicating that the calcined shell powder content was 3.0 parts by weight or more to have a high anti-tackiness property.
Next, the film materials of examples 1 to 5 contained calcined shell powder in an amount of 3.0 parts by weight or more, and had an antibacterial activity against staphylococcus aureus and escherichia coli of more than 95.0%, but the film materials of comparative examples 1 and 3 in which calcined shell powder was not added and comparative example 2 in which the amount of calcined shell powder added was insufficient had an antibacterial activity of less than 60.0%.
In addition, the puncture resistance of the film material (examples 1 to 5) to which a sufficient amount of calcined shell powder (3.0 parts by weight or more) was added was higher than that of the film material (comparative example 2) to which calcined shell powder was not added (comparative examples 1 and 3) and to which an insufficient amount of calcined shell powder was added, and was more than 4.2N, indicating that the high anti-tack antibacterial film material of the present invention has better puncture resistance.
In addition, the rupture strength of the thin film materials of examples 1 to 3 containing calcined shell powder was slightly decreased compared to the thin film materials of comparative examples 1 to 2, but it also means that the highly anti-adhesive antibacterial thin film material of the present invention may be easily decomposed by organisms, and has a potential to be an environmentally friendly material.
In summary, although the present invention has been described with reference to specific components, specific processes, specific products, or specific evaluation methods, the highly anti-sticking antibacterial film composition, the highly anti-sticking antibacterial film material containing the same, and the method for manufacturing the same, it will be apparent to those skilled in the art that the present invention is not limited thereto, and the present invention may be carried out using other components, other processes, other products, or other evaluation methods without departing from the spirit and scope of the present invention.
While the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
