Plastic Vs Glass Blender Jar – What is the Difference?

When you are off to choose a new blender, you realize that it is not that straightforward and simple process. The very next thing you’ve got to struggle with right after selecting the brand of blender you need is the material it’s made from. However, one factor that people would generally neglect when shopping for blenders is the material of the blender pitcher/jar. And that’s probably because the jar does not do blending itself, it’s just a container to place your food in, right?

And while the jar itself doesn’t really affect the machine’s blending ability, it is still an essential section of the blender simply because it’s where you drop all of your materials and where the blending action actually takes place. The blender jar material can also have a significant effect on the food items that you are blending.

People who just want the best blender for juicing would undoubtedly consider the type and material of the jar. Well, which one to select from plastic vs. glass blender jar, and which one is better? Let’s find out!

Plastic Blender Jars:

The polycarbonate blender container, found in most commercial blenders, is probably the most common and popular jar type. The least expensive blenders appear to have polycarbonate plastic pitchers, whereas the more costly versions have jars made of either copolyester or some other form of high-quality plastic.

Although the perks of blenders with glass jars are hard to deny, however, it is reassuring that any high-performance and commercial blenders do not use glass. All Vitamix and Blendtec blenders also use a sturdy plastic made of polycarbonate for their high-end machines. There is a wide range of plastic jars in terms of quality and durability, so it often gets confusing, and people stick to glass jars.plastic blender

The most significant benefit of a plastic jar is its comparative lightness and longevity. Even if it falls down accidentally on the floor, it’s always going to come out in one piece without any scratch or dent. Besides, the plastic blender jars are often cheap. Moreover, many people prefer the easier-to-read measurement labels on plastic blender jars, since a plastic container is much less reflective than its glass equivalent.

While the use of a plastic blender jar has many positive aspects, there are also few drawbacks that can not be ignored. Firstly, due to the blending operation, plastic blender jars appear to display scratches or some other marks. Secondly, plastic jars are much more likely to retain food smells and discoloration; thus, it will take a bit of diligent washing and cleaning to eliminate the odor and persistent stains. Moreover, there is a risk that certain plastic blender jars can contain BPA, which is a chemical used in many plastic products that can damage your health.

Advantages of Plastic Blender Jars:

  • Lightweight and much easier to carry and move around
  • Plastic pitchers have more capacity than glass pitchers
  • Affordable price tag
  • Replacement is much easier and cheaper
  • Does not break easily
  • Shatter-proof and Scratch-resistant
  • Sturdy and durable for longer run
  • Preserve taste and smell better

Disadvantages of Plastic Blender Jars:

  • May leach chemicals such as BPA to affect your health
  • Retain odor of food for long time
  • Cheap plastic jars are prone to scratches and ugly marks
  •  Likely to discolor easily
  • Can not withstand very high temperature

Glass Blender Jars:

Many people prefer the glass jar since it looks much nicer, holds its clarity, has a timeless charm, and feels better than its plastic equivalent. However, a glass blender jar is certainly more costly, relative to a plastic blender jar. It is perhaps its aesthetic appearance that many folks consider appealing, and they choose such a kind of jar over other blender

Numerous outstanding high-performance blenders come with glass jars instead of plastic ones. There is also an explanation for that – while glass can break very easily when fallen down or maltreated, it appears to be more durable than many plastics but not as robust as co-polyester. Also, glass does not retain scents, scratches, or stains as readily as plastics.

A major reason people are deploying glass jars is for health purposes. Even though most plastic blender jars are without BPA, they are still plastic, and glass jars eradicate the concern. Besides, a glass jar isn’t as easy to darken or stain as glass ones and does not absorb odors. Glass jars wash away all the contents since the ingredients cannot penetrate the glass. Moreover, glass persists well under heat or heated products.

The trade-off, undoubtedly, is cost. Glass jars cost much more than plastic pitchers of similar size and type. Glass pitchers are prone to crack propagation and breakage, so just be cautious not to drop it or slip it, particularly while you are holding it or washing it with your hand. Although many people would not mind the glass’s sheer heaviness, some may find the weight a little concerning. A glass jar is also more likely to injure anyone if it lands on them. So, aim for blenders with a solid foundation and a decent center of gravity.

Advantages of Glass Blender Jars:

  • Great durability and sturdiness
  • Highly resistant to scratches and ugly marks
  • Does not really impact the food
  • Healthier and free from all sorts of chemicals
  • Environment friendly and dishwasher-safe
  • Glass jars do not retain food color, odor, and smells
  • Does not discolour at all
  • Transparent and clear markings

Disadvantages of Plastic Blender Jars:

  • Bulky and heavier than plastic pitchers
  • Can easily break if dropped
  • A lot pricier than plastic counterparts
  • High-end blenders don’t usually deploy glass jars

Stainless-Steel Blender Jars:

While it is not the focus of our review, however, we will have an honorary mention of the stainless-steel pitcher, which is most respected in professional and restaurant kitchens. The stainless-steel container is almost unbreakable; however, this comes at the cost of never watching the blending process and the quality of the mixture.stainless steel blender

Many high-quality metal blender containers are made up of stainless steel. The exterior has a stylish and somewhat modern aesthetic that certainly demands a hefty price tag. As the metal is a good conductor of temperature, stainless-steel jars tend to perform stronger when it comes to maintaining the warmth or coldness of the blended food products. That’s why so many skilled bartenders choose to make cocktails, margaritas, and other premixed drinks using this container.

On the flip side, there are several disadvantages like it can dent easily if it falls down or you knock it with some heavy object. Another drawback is that it’s not transparent; therefore, you won’t be able to see ingredients, labeling, texture, or progress of the blending action. For some cooking enthusiasts, this is a problem, while for others, it’s not a concerning matter as long as they conform to the maximum level of blending specified by the brand.

Advantages of Stainless-Steel Blender Jars:

  • Lightweight and extremely durable
  • Retains the warmth or coldness of the ingredients
  • Does not retain odor, smell, and color of the food
  • Free from all sorts of harmful chemicals
  • Scratch and shatter-resistant
  • Dishwasher friendly

Disadvantages of Stainless-Steel Blender Jars:

  • Hefty price tag
  • Can easily dent if dropped
  • Jar is not transparent like above two options
  • Measurement labeling is totally useless
  • Can not monitor the consistency of blended food

Plastic Vs Glass Blender Jar – Which One is Better?

There are pros and cons for both types of jars, be it plastic or glass. However, the best jar type’s choice shall depend on your personal preferences, along with your requirements.

Compared to blenders with glass containers, a plastic jar is less prone to shatter and is relatively lighter in weight. The lightweight feature also allows the blenders to hold somewhat more giant volumed jars without compromising on the overall structure’s strength. The general cost of a plastic jar is lower than its glass counterpart; however, it can vary based on the brand being compared.

However, there are some downsides to plastic jars, which add to why certain people choose Glass jars for their blenders. A glass blender might be more massive but provides for a scratch-resistant and stain-resistant surface. This makes for an easy dishwasher based or manual cleaning. Glass jars are also more heat resistant than plastic, which can not tolerate higher temperatures.

The most crucial factor to consider is how you desire to use your blending machine, in terms of velocity and type of food you will be blending. In the end, the kind of content material you use is primarily a matter of personal choice. If your biggest concern is your health, then you must opt for the glass or stainless-steel pitcher. However, if you are into high-end machines, like the Vitamix or Blendtec, then a plastic jar is the best option to go with.
