What Are the Raw Materials of Plastic Bottles?


                      


Plastic goes through a manufacturing process to end up as bottles for liquid substances such as milk, soda, motor oil and shampoo, and for dry products such as medications and nutritional supplements. In its raw state, plastic is made up of a range of organic polymers, including polyethylene and ethylene. In a soft state, plastic can be molded into the desired shape and then cast into a solid state.

The different raw materials of plastic bottles include polyethylene terephthalate and high-density polyethylene. If you have a plastic bottle, check the base of it for the resin identification code to find out what it is made of. This code is designed to help you recycle plastic bottles in the correct way.

Polyethylene Terephthalate

A plastic bottle made of polyethylene terephthalate has the resin identification code 1. Also known as PET, PETE or polyester, it is often used for carbonated beverages, water and food products because it is strong and light. Like most plastics, PET is made from petroleum hydrocarbons, formed as a reaction between ethylene glycol, a colorless viscous hygroscopic liquid, and terephthalic acid, an organic compound. During the production process, PET polymerizes to form long molecular chains.

High-Density Polyethylene

The resin identification code 2 denotes high-density polyethylene (HDPE). It is economical and yields an efficient moisture barrier, making it the most widely used material for plastic bottles. It is made from petroleum, a naturally occurring liquid found in geological formations beneath the Earth's surface. HDPE is resistant to many solvents and has a high density-to-strength ratio, making it the ideal plastic for reusable and recyclable bottles. It is also used to make pipes, lumber, fireworks and plastic bags.

Low-Density Polyethylene

Low-density polyethylene (LDPE) has a similar makeup to HDPE but is more translucent, less chemically resistant and less rigid. LDPE, which has the resin identification code 4, is made from the monomer ethylene and is most commonly used to make plastic bags, but it can also be found in detergent bottles, dispensing bottles, and squeezable bottles for foodstuffs like honey and mustard.

Polystyrene

Polystyrene (PS) is a synthetic aromatic polymer made from the monomer styrene. It may come solid or foamed and has the resin identification code 6. As a rigid plastic with an excellent moisture barrier and low thermal conductivity, PS is often used to make bottles for dry products, such as vitamins and aspirin. Some milk and yogurt drinks may also come in PS bottles.

ABOUT US :

Hydrte was launched in 2019 with one main goal in mind, to produce a water bottle that helped significantly reduce single-use plastic consumption, whilst being stylish & convenient.

One million single-use plastic water bottles are sold every 60 seconds worldwide.

This is a huge problem for our planet.

60% of these bottles end up in landfill or even our rivers and oceans. 

The Hydrte bottle was designed in London, inspired by the busy lifestyle of the city itself. The shape of the Hydrte bottle is unique, practical and convenient.

Its flat slim shape was designed to offer a high-quality feel, whilst maintaining a sleek look. It comfortably fits into handbags, laptop bags, backpacks and just about anywhere else!

You really can stay hydrated whenever, wherever!

For the recommended daily amount of hydration, use tap water and this reusable bottle instead of buying bottled drinks, you could save an average of around £800/$1,000+ per year.

It’s time to stay hydrated in style

5 OVERLOOKED BENEFITS OF DRINKING WATER

Image
You’ll be happy to know that water provides plenty of benefits. And we want to give you 5of the often-overlooked benefits of drinking water. 1. INCREASES BRAIN POWER AND PROVIDES ENERGY Need a mental boost? Next time you feel your mental performance diminish, skip the cup of coffee and drink some water. One of water’s many benefits is an increase in brain power. Since your brain is made of 73% water, drinking it helps you think, focus, concentrate, and stay alert. As a result, your energy levels also improve. According to research, it doesn’t take much to feel the impact of dehydration. “Being dehydrated by just 2% impairs performance in tasks that require attention, psychomotor, and immediate memory skills, as well as assessment of the subjective state.” BSX Technologies lists four ways dehydration affects your brain: 1. Dehydration affects your mood. 2. Dehydration reduces your cognitive and motor skills. 3. De...

Do you Buy Recycled? Make thoughtful purchases that actually help the planet

  Do you Buy Recycled? Make Thoughtful Purchases That Actually Help The Planet Did you know that recycling doesn't end at the bin? If you're like most people, you probably already recycle your empty containers at home and on the go. Thank you! Recycling is such an important step to keep valuable materials out of the landfill and in the economy, preventing pollution while creating green jobs. Now it's time to complete the cycle of recycling. It's just as important to buy products made with recycled content as it is to recycle. Our consumer choices have an impact far beyond the register. We simply have to stop extracting so much from the Earth. To unlock all those environmental and economic benefits that come with recycling, your recyclables have to transform into new products. In other words…  you already recycle. Now it's time to Buy Recycled. As in previous blogs I have already discussed on plastic recycling, and it's importance, I urge all to buy recycled item...

Global CO2 Pollution Returns To Pre-COVID levels

 Global CO2 Pollution Returns To Pre-COVID levels Global carbon dioxide (CO2) emissions have returned to pre-pandemic levels and then some, threatening to put climate treaty targets for capping global warming out of reach, the International Energy Agency says. Energy-related emissions were two percent higher in December 2020 than in the same month a year earlier, driven by economic recovery and a lack of clean energy policies. Long-term exposure to air pollution may be linked to 15 percent of COVID-19 deaths globally, according to a new study. Reduce Emissions’ The authors stressed that attributing COVID-19 deaths to air pollution did not mean that pollution itself was killing people with the disease, although they did not rule out such a cause-effect linkage. Jos Lelieveld, of the Max Planck Institute for Chemistry, told the AFP news agency that the research suggested “the pollution particles are a co-factor in aggravating the disease”.
