How does stretch stretch film change "waste" into treasure

       We all know that many products will try to tie them together before shipping. Although the rope can be done, it will not work during transportation. Instead of packing them with a stretch of stretch film, you can not only tie them. Together, it can also be dust-proof and moisture-proof to ensure that the product is not damaged.
                         
    Stretch film has excellent tensile strength, puncture resistance, tear resistance, high transparency, tight packaging and no looseness. It is widely used in chemical products, electronic product boxes, ceramic products, electromechanical equipment, paper products, etc. Bundling. Thanks to the superior winding force and retractability of the film, the product can be compactly fixed and bundled into one unit, providing excellent primary protection for the product. It can ensure the safety and stability of the product, and it can prevent dust and moisture and ensure the product is not damaged.

     The "predecessor" of this stretch film is waste plastic. Under the influence of advanced technology, the waste plastic is transformed into a wrap film. This film is different from traditional packaging materials and is entering the packaging market at an alarming rate. It is increasingly favored and widely used in the logistics and paper industry. Large pastoral herdsmen in the winter, as small as Mercedes-Benz, BMW car headlights, can see it.
                   
    Stretch-wrapped film is thinner and does not need to be glued, so it is simpler in the manufacturing process. However, in the face of piles of plastic waste, the stretch-wound film used for packaging is not only cost-effective but also A great packaging effect.

How to eliminate white spots on aluminized film?

The aluminized film is coated with a layer of metal on the basis of the bottom mold. It is a high-grade film product in the protective film industry. Its use is mainly for the packaging of advanced batteries and lenses, especially some need to be with water and For products that are isolated from air and sunlight, aluminized films are the first choice for their packaging.

    There are many white spots on the aluminized film, some of which are the reasons for the production process, and some are the reasons for not keeping it properly after production. In short, white spots cause great losses to the product itself, so how to eliminate these white spots , the knowledge required for both the manufacturer and the manufacturer.

    1. Different batches of inks increase the particle size detection index and strictly control, especially the size and particle size distribution of the full-bottom inks are not used outside the standard range; choose an excellent stable supplier.

    2. A special adhesive for aluminized film is used. The surface adhesive of the aluminized film composite adhesive has a low surface tension, and the coating spread effect on the surface of the aluminized layer is significantly superior to that of the general-purpose adhesive. The use of aluminized rubber makes it easy to control the leveling of the glue and has an ideal coating condition. From the adhesive coating state, the use of aluminum-plated glue can eliminate the possibility of white spots.

    3. The viscosity of the glue has a certain matching relationship with the number of the wire roller. If the matching interval is too large, the coating state of the glue will be destroyed, and the generation of "white spots" is more concerned.

    4, using aluminized film coating. The coating process usually adopted is a printing film (ink surface) coating, and a special coating method is adopted here to avoid the problem of uneven penetration of the ethyl layer on the ink layer, and avoid the problem of uneven penetration of the ink layer by the ethyl ester. At the same time, the applied adhesive can cover the surface of the aluminum layer sufficiently uniformly, so that the white point can be well eliminated. However, this process has its own limitations. First, it is limited to the composite of VMPET, while other aluminized films are subjected to heat in the oven and will be stretched and deformed under the action of tension. Secondly, a certain peel strength will be sacrificed. .

     5, flexible packaging companies must adhere to the regular cleaning system of coating rolls, master the correct coating roller cleaning method. When producing a full-white or light-bottom printing film, pay attention to two points. First, thoroughly clean the blade, coating roller, flattening roller, etc. before production.

    6. The adhesive should be thoroughly dried. Because the barrier property of aluminum plating is better, if the adhesion in the composite film is not completely dried, after the composite film enters the curing chamber, a large amount of residual solvent needs to be quickly released, and under the barrier of the aluminized film, a bubble is formed. . There may even be no white spots when the machine is off, and white spots appear after the aging.

Different uses of CPP protective film in various industries

      CPP protective film has very important practicality in various industries. More and more industry packaging and engineering are focused on CPP protective film. CPP protective film has CPP matte protective film, CPP transparent protective film, CPP extinction protection. Membrane, CPP co-extruded composite film, etc., have different uses in various industries.

                          

    Use of CPP protective film in the medical industry: The production line is required to be installed in a sterile room to prevent the product from being contaminated by any form, and does not contain hygienic properties such as migration of harmful substances. After aluminum plating, it is combined with BOPP, PET, BOPA, etc. as a package for tablets or powder medicines; and is co-extruded with high-barrier materials such as EVOH to produce infusion bags, blood collection bags, and the like.

    CPP protective film for pesticide use: The special solvent is used to improve the solvent resistance, heat seal strength and impact strength of CPP film. It is applied to the packaging of pesticides such as emulsifiable concentrate. The usual flexible packaging structure is CPP/AL/BOPET. And CPP/PET aluminized/BOPET.

    CPP protective film and PE co-extruded composite film use: CPP film produced by modification can directly use LDPE and other film materials for extrusion compounding, which not only ensures the fastness of extrusion compounding, but also reduces the cost of compounding.

    Highly transparent and flexible film processed by using CPP protective film as a substrate: CPP protective film has high transparency and high impact resistance by using co-extrusion and blending technology, and has extremely soft hand feeling and excellent resistance. Puncture performance and low temperature resistance, mainly used for food packaging after frozen storage, also used in high-end clothing, T-shirts and underwear, and other heavy packaging.

    The CPP protective film can be processed into a biodegradable film, and its use: a CPP degradation film prepared by adding a degradation masterbatch to the PP, and being substantially degradable to inorganic matter by the soil under the natural conditions for about 7 months to 12 months. absorb. At present, some European companies have successfully developed such masterbatch, and some domestic cast film plants are testing.

Introduction to PET Aluminized Film

       PET aluminized film is widely used in beverages, pharmaceuticals, alcohol, cigarettes, cosmetics, food, gifts, and other packaging. It is the basic raw material for printing composite industry. PET aluminized film mainly produces high vacuum aluminum film (including color film). High vacuum aluminum-plated paper (including color aluminum-plated paper), anodized aluminum, aluminized non-woven fabric, cigarette liner paper, water-soluble coating for aluminum plating.

                   

       PET Aluminized Film Processing: A composite flexible packaging material is formed by vaporizing and vaporizing aluminum in a high vacuum state by high temperature to cause aluminum vapor to deposit and deposit aluminum vapor onto the surface of the plastic film. The aluminized film has excellent gas barrier properties, moisture barrier properties, light blocking properties and aroma retention properties, which can extend the shelf life of the contents. Because of its beautiful appearance, it can also replace aluminum foil to a certain extent, reducing the cost of packaging, and is often used in ordinary small food packaging, such as puffed food, biscuits, mustard and the like. It is also frequently used in high-end packaging such as medicine, tea, and milk powder.

There are two common pvc particle density testers. They are MDJ-300A pvc particle density tester and MDJ-600A pvc particle density tester. The MDJ-300A type pvc particle density tester has a measurement range of 0.01 to 300 grams and an apparent density of 0.001 grams per cubic centimeter. As for the MDJ-600A type pvc particle density tester. Its measurement range is larger than that of the MDJ-300A pvc cable density tester, which ranges from 0.01 to 600 grams. The apparent density analysis is the same as the MDJ-300A pvc particle density tester, which is 0.001 gram per cubic centimeter.

My product was returned because PVC pellets are not stored well.

PVC plastic pellets are inexpensive, highly effective, environmentally friendly and non-polluting, and are widely used in agriculture and industry. However, after many manufacturers purchase PVC plastic pellets, the quality of PVC pellets is degraded due to some mistakes in the transportation and storage process, and the production of unqualified PVC products causes a large amount of unnecessary losses. Today, Runte Rubber & Plastics is a professional PVC manufacturer to teach you how to transport and store PVC plastic pellets.

Store PVC plastic pellets

First choose a cool, ventilated location. Keep away from direct sunlight in a cool place to avoid fading after prolonged exposure to sunlight or quality problems. The ventilated place can effectively prevent the material from getting wet. The temperature difference between indoor and outdoor is too large, so it is easy to produce moisture. Once the PVC plastic particles are damp, its quality will be greatly affected, so choose a cool and ventilated place. In addition, the preparation of fire prevention and anti-corrosion also needs to be done. Therefore, it is very important to prepare some fireproof materials in the storage room where PVC plastic particles can be stored. At the same time, it is possible to stay away from the fire source and prevent it from happening.

Transport PVC plastic pellets

When PVC plastic is transported by granules by PVC plastic granule manufacturers, sun protection should be done. The summer sun is strong, and the PVC plastic particles are exposed to sunlight for a long time, and it is easy to appear brittle and other quality degradation. Therefore, in the transportation of the manufacturer, the plastic granules can be covered with canvas or the like, or the transport vehicle with the carriage can be selected, so that the PVC granule product can be protected to a large extent.

In summary, in the process of PVC transportation and storage, it is necessary to do a good job of protection to ensure the quality of PVC particles, so as to produce high quality PVC products.
