Is the bucket used to deliver bottled water healthy? Can it be used?

The barrels (mainly made of PC) used for delivering bottled water are relatively healthy when used in compliance and can be used safely. However, pay attention to materials, usage specifications and maintenance points. Common barrel bucket materials and safety 1) The mainstream material is PC (polycarbonate). Food-grade PC buckets meet relevant health standards. No harmful substances are separated out during normal use and can be used repeatedly.

Unhealthy and unusable barrels PC barrels made from recycled materials or recycled plastics: In order to reduce costs, some illegal merchants use recycled materials or recycled plastics to produce PC barrels. These "black heart barrels" may contain bisphenol A substitutes bisphenol S, bisphenol F, etc., as well as other toxic and harmful substances, such as antioxidants, plasticizers, nonylphenols, heavy metals, etc., which pose health risks and cannot be used.

Whether the barrels used for delivering bottled water are healthy and usable needs to be judged based on the material and usage conditions, and cannot be generalized. The details are as follows: Barrels made of regular materials are healthy and can be used for bottled water. Common materials for plastic buckets are PET and PC.

Which bucket of large water is not easy to break

At present, large buckets of water made of PC and PET on the market are relatively less likely to be damaged. PC, or polycarbonate bucket, is the mainstream bottled water container in the current market. It has high transparency, strong impact resistance, tough and durable texture, can withstand certain external impact and internal pressure, and is not easy to break during normal handling and use. The bucket made of PET, or polyethylene terephthalate, is lighter in weight, has higher overall strength, stable chemical properties, and has good fall resistance, which can avoid cracking after collision to a certain extent.

During use, if it is impacted by a large external force, it may be easily damaged. Stainless steel barrels: Although they are strong and resistant to pressure, they are costly and heavy, making them inconvenient to handle. Moreover, if you are in contact with water for a long time, problems such as rust may occur and affect the water quality.

Generally speaking, vats made of PC (polycarbonate) are relatively strong. The advantages of PC barrel are strong and durable: PC material has high strength and toughness, can withstand greater pressure and impact, and is not easy to damage. In daily use, even if it is subjected to a certain degree of collision or friction, it is not easy to break or deform. Good temperature resistance: It can be used over a wide temperature range and can withstand both high temperatures and low temperatures.

Currently, the large barrel purified water barrels on the market mainly use polycarbonate (PC) and PET (polyethylene terephthalate): it is the most widely used barrel body material currently and has the advantages of high transparency, strong impact resistance, high and low temperature resistance. It can maintain structural stability within the temperature range of-20℃ to 120℃, is not easy to deform and rupture, and meets food hygiene standards and can ensure water quality safety.

Which is the safest plastic for bottled water?

Among the plastic materials for bottled water, PC material (polycarbonate) is the safest and suitable for long-term use. There are three common materials for plastic barrels of bottled water: PC, PP, and PET. PC material has the highest stability, is resistant to high temperatures and does not contain bisphenol A. It can be directly filled with boiling water. PP material is second, which is safer for short-term use, but may be slightly deformed at long-term high temperatures. PET material is not resistant to high temperatures and easily releases harmful substances. It is only suitable for disposable bottled water and cannot be reused.

At present, PC (polycarbonate) plastic packaging is still widely used in regular bottled water on the market. PC material, the mainstream packaging material for regular bottled water, has the characteristics of high strength, impact resistance, can withstand high temperature disinfection at 137 ° C, and excellent sealing performance. It can ensure the quality and health and safety of bottled water during transportation, storage and cyclic filling. It is the main packaging material for regular bottled water cyclic filling, and the state also allows it to be used for the production and filling of bottled drinking water.

However, if pet plastic bottles are used repeatedly many times, or for more than 10 months for a long time, some harmful substances may be produced. Therefore, long-term repeated use is generally not recommended. In addition, it is not recommended to fill high-temperature water, which will also cause pet plastic bottles to produce harmful substances. In general, from a safety perspective, PC is relatively better than pet. PC is often used to make water cups and is relatively safe to hold high-temperature water. Buckets and bottles made of pet are often used to hold low-temperature liquids.

From the perspective of plastic particle pollution, tap water that meets standards is usually safer than barreled purified water after boiling and filtering, but attention should be paid to the quality of the water source and treatment methods; barreled water has problems such as container material, production and transportation, and pollution of drinking fountains. The content of plastic particles is generally higher.

How long is the service life of pc water bottled drinking water?

The normal service life of PC buckets for storing drinking water is 2-5 years. The specific duration is affected by the quality, use environment and maintenance conditions. The materials and processes of high-quality brands of PC buckets are more guaranteed, and can reach a 5-year service cycle under normal use; If it is a poor quality bucket, problems such as aging and deformation may occur after about 2 years of use. If the bucket is placed in a cool and dark place to avoid high temperature exposure and scratching with sharp objects, and at the same time, regular cleaning and disinfection can be carried out, it can delay the aging of materials and the growth of bacteria, and extend the service life.

The normal service life of PC water barreled drinking water is usually about 2-3 years, and the reference ranges under different standards are slightly different. According to the industry standard QB/T 2460 - 1999 "Polycarbonate (PC) Drinking Water Tanks", the service life of PC barrels is generally 3-5 years; however, if calculated from the production date, its storage life cannot exceed two years. Based on the regular use in the industry, the actual service life is generally 2 to 3 years.

The reasonable service life of household PC buckets is mainly affected by use scenarios and maintenance conditions. The normal cycle is 18-24 months, and the industry standard reference life is 3-5 years. At the same time, it is necessary to judge whether to replace it based on the state of the bucket body. There is no uniform fixed value for the service life of PC buckets and will be affected by multiple factors.

The normal service life of bottled drinking water buckets made of PC is usually 2 to 3 years. The actual use time will be affected by many factors: the frequency of use If the bucket is frequently turned around, the wear and aging of the bucket body will be accelerated, and the service life will be shorter than normal.

PC buckets are not recommended for long-term use to store drinking water. Generally speaking, it is safer to use them for 1-2 years. PC material characteristics PC material has advantages such as good transparency and impact resistance. However, PC-made buckets may release bisphenol A (BPA) during use, especially when holding hot water or storing drinking water for a long time. Bisphenol A is an organic compound. Excessive intake may have adverse effects on human health, such as it may affect the endocrine system.

Is bottled water still widely packaged in PC plastic on the market?

1. At present, regular bottled water on the market is still widely packed with PC (polycarbonate) plastic packaging. PC material, the mainstream packaging material for regular bottled water, has the characteristics of high strength, impact resistance, can withstand high temperature disinfection at 137 ° C, and excellent sealing performance. It can ensure the quality and health and safety of bottled water during transportation, storage and cyclic filling. It is the main packaging material for regular bottled water cyclic filling, and the state also allows it to be used for the production and filling of bottled drinking water.

2. The shelf life of unopened barreled mineral water is affected by the packaging material, and the differences are obvious. The mainstream packaging on the market is mainly divided into three categories: PET plastic barrels: It is the most common barreled water packaging, such as Wahaha and Nongfu Spring. The regular barreled water is mostly made of this material. The unopened shelf life is generally 1-2 years, and most brands label it as 1 year.

3. The standard production and manufacturing process of barreled water buckets is generally divided into 7 core steps. Raw material preparation Currently, mainstream barreled water buckets use food-grade polycarbonate (PC) plastic particles as raw materials. This material is safe and non-toxic. It has good transparency, impact resistance and temperature resistance, and can meet the storage and use requirements of barreled water. Before production, it is necessary to ensure that the quality of the particles meets food contact safety standards.

4. Big blue bottled water bottles are mainly made of food grade polycarbonate (PC), and some may also use high-density polyethylene (HDPE) modified plastics. Polycarbonate (PC) barrels are produced from new food-grade polycarbonate raw materials. The appearance is transparent and smooth, the body is light blue, and the knocking sound is crisp and tough. This material is mainly used for drinking pure water in cans. It has the characteristics of high strength and wear resistance, and has a damage life of more than 3 years.

5. PET material is often used in disposable bottled water packaging. At high temperatures (such as exceeding 70℃), it may release trace amounts of harmful substances, and long-term use will cause scratches, oxidation and brittleness. PC materials are relatively resistant to high temperatures, but bisphenol A PC barrels have been banned in China since 2022. The new alternative materials are more safe, and the service life still needs to be paid attention to.

What kind of water can bottled water be used all the time

1. There is no bucket that can be "always used", because any container will be worn out due to factors such as material aging, wear, corrosion, etc., and cannot maintain its function permanently. When selecting a bucket, attention should be paid to the durability of the material, maintenance methods and usage scenarios to extend its service life.

2. Water barreled water made of PC (polycarbonate) and HDPE (high density polyethylene) can be used all the time under the premise of cleaning and maintenance, but attention should be paid to the service life and material quality. PC bucket: Features: PC bucket is resistant to high temperatures and has good stability. It is a mainstream product in the barreled water industry.

3. Formal and qualified barreled buckets can be used repeatedly for a long time on the premise of complying with specifications for use and maintenance, but there are certain risks, and not all situations are suitable for long-term reuse.

4. If the body of the PET bucket is not deformed, cracked, and has no pungent smell, it can continue to be used after simple cleaning and disinfection. The chemical properties of the PET material itself are relatively stable. As long as it is not contaminated or physically damaged, it can be filled with water again after being idle for a few months. You can first clean the inside of the bucket with detergent, and then rinse it with a lot of water to ensure that there are no detergent residues.
