Every day, a large number of plastic containers in different types of shapes and sizes pass through the hands of consumers, but hardly any customer pays attention to the actual construction material they are made of. HDPE and PET are two of the most common materials used to produce a comprehensive range of containers utilizing single stage molds and ACME molds

This blog discusses some of the most important aspects associated with HDPE and PET in the following points:

Plastic containers made of poor or low-quality plastic cannot be considered safe and durable at all. It comes true especially in the cases of medicines which when stored improperly in lower-grade containers might prove to be very dangerous for children as well as pet animals. Faulty child-proof caps often let children access medications, resulting in overdoses and many times incurable health problems. Each year, more than 34,000 children around the globe are admitted to hospitals due to the problems caused by unsuitable medicine consumption. 

There is no dearth of unsafe plastics that cause lethal toxins to leach into the concerned product. Food sources and fluids put away inappropriately can ingest the poisons, particularly when warmed or stored over an extensive stretch of time. The significance of utilizing the right food-grade plastic can’t be undervalued. HDPE plastic is as of now thought to be a low-risk plastic with an okay of leaching. PET plastic is also endorsed as safe for food and refreshment contact by the FDA and other administrative organizations all through the world and has been in use for over 30 years.

PET Plastic Containers 

Polyethene terephthalate generally known as PET or PETE plastic or polyester is clear and sturdy yet lightweight. It’s generally utilized for drink containers, salad dressings, cleanser bottles, peanut butter, milk containers, cooking oils, and food stockpiling. Thirty years of testing have demonstrated this plastic to be ok for contact with food packaging, beverages, and drugs. Since it is impervious to miniature living beings and won’t respond to food sources or biodegrade, and is 100 percent recyclable, PET is one of the most famous plastic variants to utilize. As a matter of fact, PET plastic is the most reused plastic in the U.S. and around the world. The FDA and other health-related renowned associations consider PET quite secure. It doesn’t contain bisphenol-A (BPA) or phthalate.

PET jugs or containers can be decorated and shaped into a wide assortment of shapes and sizes. Their high lucidity takes into consideration great product visibility and they are effectively hued to supplement a brand name. While you’re searching for the security of products like drugs or nutraceuticals, golden-shaded bottles offer high protection from UV rays. 

HDPE Plastic Containers 

High-thickness polyethene, or HDPE, is generally utilized in both unbending and adaptable items. Its flexibility permits it to be utilized for all that from hard caps to capacity holders to packs. Lightweight yet solid and impact-safe, this plastic has swapped numerous metals and wood for playground gear, decks, and vehicle parts, yet remains exceptionally recyclable. It is FDA-endorsed and ok for food, fluids, and drugs, and doesn’t contain BPA or phthalate.

A significant property of HDPE plastic is its capacity to endure cold temperatures. HDPE plastic can get through long-haul temperatures of up to – 100 degrees Fahrenheit. This permits items, for example, food and refreshments to be frozen for use/application in the future. It likewise can endure temperatures between 212 and – 220 degrees Fahrenheit for brief timeframes, making it once in a while reasonable for autoclave disinfection.

What’s the Difference? HDPE versus PET

People often ask about the major differences between HDPE and PET plastic containers. PET plastic is clear and glass-like while HDPE plastic is more misty and adaptable. Both are protected and are ideal choices for consumables. HDPE bottles give great pressure break resistance and impact strength alongside a uniform wall thickness for better marking and appearance. PET plastic compartments are made utilizing a two-stage infusion blow-forming process. Clear PET jugs offer an extraordinary liquor, dissolvable, and dampness obstruction.

Barrier Capabilities 

Albeit PET normally has obstruction capacities sufficient for a considerable number of items, a few items need extra boundaries to keep up with carbonation levels and to safeguard against oxygen pervasion that could adversely influence the product’s period of usability. The PET industry has met the big challenge with a multipronged provision that incorporates monolayer obstruction tars, coatings and multi-facet holders. All barrier innovations are either latent or dynamic. A detached hindrance innovation blocks oxygen from entering through the walls of the holder and carbonation from leaving.

Then again, a functioning framework assimilates the oxygen present in the item, in the headspace of the holder and the sidewalls of the compartment. This is typically through an oxygen scrounger that ties to and obliterates the oxygen atoms. While an uninvolved boundary framework performs reliably over the long run, a functioning barrier framework has its own timeframe of realistic usability. Multi-facet remains the most settled barrier innovation. It, in a real sense, includes infusing at least one centre layer between the two outside PET layers. The centre layers might be reused PET, uninvolved barrier material, dynamic searching material or any blend of the three. Multi-facet arrangements are profoundly powerful and effective, yet extra capital investment is important to furnish standard infusion frameworks with multi-facet capacity.


ADS is one of the largest single stage molds manufacturers in India. The single stage molds are used for making containers and bottles of varied shapes and sizes made of materials such as PET, PP, PC, TRITAN, and many more. The company offers a range of high-quality ACME molds for Single Stage ISBM for the manufacturing of PET, PP, PC and TRITAN bottles. The company provides better mold matrix optimization that always results in enhanced volume production of containers. At ADS, quality is not merely a statement but a mission. The company believes that each and every variable or component involved in the formation of a mold holds extreme importance for its final success.
