PP Plastic Jar: The Complete Profile

A PP plastic jar is a container made from Polypropylene, a versatile thermoplastic polymer designated by the resin identification code #5. It's one of the most common and reliable types of packaging due to its excellent safety and durability profile. 

At a Glance: Key Characteristics

• Material: Polypropylene (PP)

• Resin Code: #5

• Typical Feel: Semi-rigid with a slightly waxy or soft texture.

• Clarity: Naturally translucent (milky or frosted appearance). Can be made opaque or clarity-enhanced.

• Key Strength: Excellent heat and chemical resistance.

Detailed Advantages & Properties

1. Heat Resistance (The #1 Feature):

   • Microwave Safe: Withstands microwave heating without deforming, making it ideal for ready-to-eat meals, syrups, and yogurt.

   • Hot-Fill Capable: Can be filled with products at high temperatures (up to 100°C / 212°F) for processes like pasteurization.

   • Autoclavable: Certain medical-grade PP jars can withstand steam sterilization.

2. Chemical & Moisture Resistance:

   • Barrier Properties: Provides an excellent barrier against water vapor, keeping contents dry. However, it has a poor oxygen barrier, which can be a limitation for some products.

   • Resistant to Oils, Fats, and Acids: Perfect for greasy foods, condiments, lotions, and aggressive household chemicals. It won't become brittle or degrade.

3. Durability:

   • Impact Resistant: Less brittle than PET or PS; it can withstand drops and impacts without cracking.

   • Stress Crack Resistant: Holds up well against the pressure of twist-on caps and lids over time.

4. Safety and Compliance:

   • Food-Grade: PP is approved for food contact by regulatory bodies like the FDA and EFSA worldwide.

   • Odorless and Tasteless: Does not impart any taste or odor to the product inside.
