How to Package Plastic Jars

You’ve probably heard of glass jars, but have you ever wondered how to package plastic jars? Glass jars look more authentic, but plastic jars have their advantages. Both plastic and glass can be recycled. Plastic jars also tend to be cheaper and don’t shatter. Glass jars are also recyclable, and consumers prefer them when they want to consume liquids or other quick-use items.


Low-density polyethylene (LDPE) plastic jars are an excellent option for packaging products that require flexible, pliable containers. Low-density polyethylene is 100 percent recyclable and great for products that need to be dispensed easily. They are also available in translucent and opaque variations, with many closures. Read on for more tips on packaging LDPE plastic jars.

LDPE is a naturally translucent, lightweight plastic. It is notable for its low-temperature flexibility, toughness, and corrosion resistance. Its flexibility makes it suitable for squeezy packaging but does not have the same structural strength and stiffness as High-density polyethylene (HDPE). Nevertheless, it can be recycled to produce lumber or floor tiles. Consider some basic tips if you’re wondering how to package LDPE plastic jars.

Low-density polyethylene (LDPE) plastic jars are a popular choice for packaging products. Because LDPE is more flexible than HDPE, it can handle higher temperatures. Its high melting point makes it ideal for microwave and dishwasher use. It’s a good choice for food packaging because it’s safe for food and is recyclable. Just be sure to label the package clearly and safely to avoid confusion.

Polyethylene terephthalate (PET)

If you are looking for a more sustainable food storage solution, consider PETE jars. PETE bottles are durable plastic containers that can be cleaned and reused. There are a few disadvantages to using PETE bottles, however. For example, they don’t provide enough oxygen to keep food fresh for many years. Hence, you should rotate your food storage with other forms of short-term food supplies.

The PET jars are made from a plastic polymer of ethylene glycol and terephthalic acid. This resin is heated and molded into almost any shape. It was first synthesized in the mid-1940s by DuPont chemists seeking polymers for textile fibers. When purchasing PET jars, look for those with an identification code on the side. They are marked with a triangle containing the number and the acronym PET underneath.


High-density polyethylene (HDPE) bottles are ideal for niche food products, nutritional supplements, and personal care items. They weigh up to 50% less than glass bottles. These jars have multiple closures, including screw caps, flip tops, and spouts. BottleStore also offers jar seals, lotion pumps, and fine mist sprayers. Each bottle is bagged and labeled with its lot number and catalog number.

HDPE packaging is available in various forms, including film, blow-molded bottles, and injection molding. Film is commonly used in snack food packaging, cereal box liners, and milk and non-carbonated beverage bottles. Injection molding is commonly used for jars, tubs, bottles and margarine, whipped toppings, and deli food. The high-density polyethylene material is highly recyclable and an excellent choice for food products.

Plastic jars made of HDPE are popular because they are durable and have good chemical resistance. At The Cary Company, we offer a variety of HDPE plastic bottle styles. These jars are suitable for use in many industries and can withstand temperatures as low as minus 40 degrees Fahrenheit. Aside from being durable, HDPE bottles also resist bursting, cracking, and rusting.


The demand for plastic jars is increasing across various end-use industries. The increasing need for lightweight, durable, and cost-effective packaging solutions is driving the growth of the plastic jar packaging market. During the forecast period, the plastic jar packaging market is projected to reach 175,770 million units, rising at a CAGR of 2.9% over the previous year. The strong demand for plastic jars in the consumer goods sector is expected to keep driving the industry’s growth.

Plastic jars come in various shapes, styles, colors, and materials. These products can be quickly packaged in a variety of ways. PET jars, for instance, are lightweight and semi-rigid. This makes them an excellent option for beauty products. PET plastic is commonly used in jars made of cooking oil, peanut butter, and soft drinks. You can choose the color and shape that matches your brand’s identity.
