 Three Common Types of Food-Grade Plastics

Plastics have become an indispensable material in modern food packaging due to their lightness,durability and ease of processing. PET,PP and PS are three popular food-grade plastics and we will explore their characteristics,advantages and disadvantages in more depth below.

1. PET (Polyethylene Terephthalate)

PET plastic boasts exceptional transparency,heat resistance and impact resistance - it even rivals glass transparency!As its transparency makes it ideal for food packaging with high transparency requirements such as mineral water bottles or carbonated beverage bottles. Furthermore,its excellent heat resistance enables it to remain stable at high temperatures,making PET ideal for microwave heating boxes.

Advantages：1.High transparency,close to glass 2.Good heat resistance,can be used at high temperatures3.Strong impact resistance,not easy to break

Disadvantages：1.Relatively high cost 2.Sensitive to certain chemicals,such as grease,alcohol,etc

2. Polypropylene Plastic (PP Plastic)

PP plastic is an extremely versatile thermoplastic synthetic resin material with excellent chemical and heat resistance properties as well as electrical insulation properties,high strength mechanical properties and wear resistance processing performance. Boiling water sterilized it makes this plastic perfect for food packaging that requires high temperature sterilization such as lunch boxes.

Advantages：1.Good heat resistance,can be used at high temperature 2.Good chemical resistance,can resist corrosion from a variety of acids,alkalis,salts and other chemicals 3.Lightweight,easy to process and transport

Disadvantages：1.Relatively low transparency2.Sensitive to ultraviolet rays and easy to age

3. PS (polystyrene)

PS plastic is a colorless and transparent thermoplastic with a high glass transition temperature and good impact resistance. It is often used to make disposable containers that need to withstand high temperatures,such as disposable foam lunch boxes,fresh-keeping boxes,etc.

Advantages：1.High transparency and beautiful appearance 2.Good heat resistance and can withstand high temperatures 3.Hard texture and strong impact resistance.

 Precautions for using glass candlesticks

Glass candle holder decoration brings warmth and romance into our living spaces while at the same time conveying cultural heritage and craft aesthetics. However,when using such candlesticks we must pay special attention to their safety in order to extend their service lives;please see the following points as considerations when using them:

1. Select an Appropriate Candle

Its When selecting a glass candle holder,be sure to select a candle that complements its size. Otherwise,the holder could overheat and even break;too large of a candle could overpower its size while too small may cause instability with its flame and pose potential danger. It is also advised to select smokeless and flavorless candles to reduce indoor air pollution.

2. Pay Attention to Placement

Glass candle holders should be placed on a stable and fireproof table to avoid proximity with flammable objects or poorly ventilated spaces. Furthermore,their bottom should provide ample heat dissipation space in order to avoid heat accumulation.

3. Avoid prolonged burning

Though glass candle holders provide greater heat resistance,it still may become overheated after long use. Therefore,we advise using no more than four hours at one time,with regular checks of their temperature to ensure safety.

4. Keep an eye out for any sudden temperature shifts

As glass candlesticks can break with sudden temperature shifts,they should not be placed in an environment with wide temperature differentials such as direct sunlight exposure or near heat sources such as radiators.

When searching for a glass candle holder,we advise considering IDEA productsmade of high-grade glass with exquisite designs and craftsmanship. Not only are our candlesticks heat resistant but they also incorporate modern aesthetic elements for added warmth in your home space. Furthermore,IDEA offers various styles and sizes so we can work together in adding beautiful romance into your life!

Why do beer bottles love dark green? A journey of history, science and taste

Idea Glass Bottles and Idea Glass Jars Creative Glass Bottles and Creative Glass Jars Glass Bottles and Glass Jars

 This is why beer bottlesare dark green

First of all,historical perspective aside, early glass manufacturing processes were not ideal and often left the product with impurities like divalent iron ions - one of which caused its characteristic light green hue. With advancements in glass production technology, people realized that though these impurities could be neutralized or removed using other chemicals, dark green glass became more desirable visually because it offers stability and tranquillity that pairs perfectly with refreshing beers.

Secondly, Dark green glass beer bottles play an integral part in protecting the quality of beer from scientific aspects. Beer contains light-sensitive compounds which react when exposed to sunlight or ultraviolet rays, leading to its oxidization, degradation, and production of an offensive "sun odor". Filtering out most UV rays through dark green glass helps minimize this reaction and preserve freshness and taste of your beverage.

In addition, Dark green glass has an ideal light transmittance rate, allowing a moderate amount of light into the bottle and brightening its contents, giving off clear and bright beer imagery, increasing display effectiveness, and creating an immersive display effect for its product. Furthermore, this color provides people with a comfortable and relaxing ambience which complements its leisure attributes perfectly.

How the commonly used plastic bottles or glass bottles are made?

Idea Glass Bottles and Idea Glass Jars Creative Glass Bottles and Creative Glass Jars Glass Bottles and Glass Jars

Do you know how the plastic bottles or glass bottles are produced? Yes,model blowing. It also known as hollow model blowing,is a rapidly developing plastic processing method.This is a processing method used in plastic manufacturing process that uses gas pressure to inflate a hot-melt parison closed in a mould to form a hollow product.The blow molding began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used.

The blow molding process consists of several standard steps:

1.The parison is installed on the nozzle of the machine, and then put into the mould, which is divided into two halves.

2.The hot air passes through the blowing head to form a billet, expanding to the shape of the mould.

3.Cool in the mould for a few seconds before demoulding.

4.Remove extra material at both ends to finalize the product.

For economic considerations, it is necessary to produce thousands of pieces per hour. Blow molding manufacturing is generally mass production. With the improvement of the automation level, the cost of equipment decreases, and one worker can control the operation of multiple automation equipment, and the labor cost is low.

Glass products are an integral part of everyday life, from exquisite glasses on our dining tables to cooking utensils in our kitchen and mirrors and windows in the bathroom. People appreciate its transparent properties that are durable yet easy to clean; yet as we browse low-priced glass products on the market, have we ever stopped to consider what secrets lie hidden behind these seemingly economical offerings?

Low-priced glass products typically rely on cheaper raw materials and processes for production, leading to impurities in the product which could affect its beauty and transparency while potentially releasing toxic substances that pose risks to human health during use. If quality standards fall short, food-grade glassware could contain heavy metals like lead and cadmium which could cause chronic poisoning over time.

Second, durability and safety of low-priced glass products cannot always be assured due to cost constraints. Due to these constraints, some low-priced products may contain defects in design and production such as rough edges and uneven thickness that make them easily breakable or cause dangerous situations like bursting during use. Furthermore, some low-priced products even use recycled waste glass in reproduction which not only compromises product performance but can cause hygiene issues as well.

As a company focusing on the research and development and production of high-quality glass products, IDEA are well aware of the importance of product quality and safety to consumers. We use advanced production technology and a strict quality control system to ensure that each product meets national and industry standards. Our glass products are not only beautiful in appearance and excellent in performance, but also safe, reliable, environmentally friendly and healthy. We call on consumers not to be fooled by low prices when choosing glass products, but to pay attention to product quality and safety.
