Q: Is the plastic case transparent or opaque?: From the use of function, the same plastic finishing box, transparent and opaque are not too much relationship, there is no difference between good and bad.

Q: How do olive nets prevent olives from getting sunburned?: Olive nets prevent olives from getting sunburned by providing shade and reducing direct exposure to the intense sunlight, thus protecting the delicate fruit from heat stress and sun damage.

Q: How can I remove the scratches on the plastic?: The main component of plastics is resin. The term was first resin secrete by animal and plant lipid and its name, such as rosin, shellac, resin is not mixed with various additives and polymer compounds. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role. Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene.

Q: How does the cost of using olive nets compare to other harvesting methods?: The cost of using olive nets is generally lower compared to other harvesting methods. Olive nets are a more affordable option as they require minimal investment and can be reused for several years. Additionally, using nets is a more efficient and time-saving approach, reducing labor costs associated with manual harvesting.

Q: What's the difference between cans and plastic bottles?: The glass bottle can be used repeatedly and is inconvenient to carry, but there are phenomena of cleaning up, cross contamination and fraud, and people can not be relieved.Plastic bottle, glass with respect to that of oxygen and carbon monoxide permeability coefficient is large, it will lead to a chemical reaction between packing objects and packaging, packaging is also due to the oxidation of the flavor deterioration occurred, and the aging of plastic products also affect the appearance quality, beautiful appearance and practicability, and environmental pollution.

Q: How many grades are there in the plastic block? How to divide?: UL is a plastic material standard test piece by spontaneous combustion flame after the combustion time, combustion speed, falling particle state to set the plastic material fire resistance rating, according to the level of quality, followed by HB, V2, V1, V0, 5V, VTM-0, VTM-1 and thin material grade, VTM-2, and foam material grade HBF, HF-1, HF-2.

Q: What are the materials for plastic bottles?: There are many ways of making polyethylene, the most common of which is the polymerization of ethylene at temperatures of 200~300 C and 1000~2000 atm. In polyethylene, no other substance is doped. This low density polyethylene obtained, soft texture, for sunlight, air, water and chemical reagents, have high stability, so no external stabilizer, plasticizer, stabilizer and plasticizer are mostly toxic or highly toxic.

Q: Do olive nets affect the quality of the olive oil produced?: Yes, olive nets can affect the quality of the olive oil produced. The use of nets during olive harvesting can lead to physical damage to the olives, causing bruising or crushing, which can negatively impact the quality of the resulting oil. Additionally, if the nets are not properly cleaned or maintained, they can harbor bacteria or other contaminants that may affect the taste and overall quality of the olive oil. Therefore, it is important to carefully consider the use of olive nets and ensure proper handling and maintenance to minimize any potential negative effects on the oil's quality.

Q: Are there any specific guidelines for removing olive nets without damaging the trees?: Yes, there are specific guidelines for removing olive nets without damaging the trees. Some key recommendations include: 1. Carefully untangling the net from the branches to avoid pulling or snapping them. 2. Using gentle movements and avoiding excessive force while detaching the net. 3. Ensuring that no branches or leaves are caught in the net before removing it. 4. Removing the net during calm weather to minimize the risk of strong winds causing damage to the tree. 5. Regularly inspecting the net for any tears or damage that may entangle with the branches and repairing them promptly. By following these guidelines, olive nets can be removed safely without causing harm to the trees.

Q: Can olive nets be used in areas with frequent frost?: No, olive nets should not be used in areas with frequent frost as they may not provide sufficient protection for the olive trees or crops from the cold temperatures.
