What Makes 110ml Wide-Mouth PP Jars the Best Choice for Packaging?

What Is a 110ml Wide-Mouth PP Jar and Why Does It Matter?

A 110ml wide-mouth PP jar is a small, sturdy container made from polypropylene (PP), a thermoplastic polymer widely recognized for its durability, chemical resistance, and food-safe properties. The "wide-mouth" design refers to an opening that is proportionally large relative to the jar's body, making it easy to fill, scoop from, and clean. At 110ml, this jar size hits a practical sweet spot — compact enough for portability and single-use portions, yet spacious enough to store a meaningful quantity of product. These jars are used across a remarkably broad range of industries, from food and beverage to cosmetics, pharmaceuticals, and laboratory applications. Understanding what distinguishes this specific jar type helps buyers and businesses make smarter sourcing decisions.

Why Polypropylene Is the Material of Choice

Polypropylene stands out among plastics for packaging due to a combination of practical properties that few other materials can match at the same price point. It has a high melting point — typically around 160°C — which means PP jars can withstand hot-fill processes and even short-term microwave exposure without warping or leaching harmful substances. This makes them particularly valuable in food packaging where contents may need to be heated.

PP is also highly resistant to a wide range of chemicals, including acids, bases, and solvents commonly found in cosmetic formulations and cleaning products. This resistance means the jar won't degrade when in contact with contents that might corrode or cloud other plastic types. Additionally, polypropylene is lightweight, reducing shipping costs for both manufacturers and end consumers. Its recyclability (labeled with resin identification code #5) aligns with growing sustainability demands in the packaging industry.

From a transparency standpoint, PP can be manufactured in natural (semi-translucent), clear, opaque white, or custom colors, giving brands significant flexibility in visual presentation. The material also accepts screen printing, labeling, and in-mold labeling with ease, supporting high-quality branding.

Key Design Features of the Wide-Mouth Opening

The wide-mouth configuration is not just an aesthetic choice — it delivers measurable functional advantages that matter across different use cases. Here's how the wide opening benefits users and manufacturers alike:

• Easy Filling: Whether filling by hand or through automated machinery, a wider aperture reduces spillage and speeds up the production line. Thick or viscous substances like creams, pastes, and gels flow in without clogging.
• Effortless Scooping: For products like protein powders, spices, or skincare balms, users can insert a scoop or spatula without difficulty, ensuring minimal product waste.
• Thorough Cleaning: A wide mouth allows cleaning brushes, sponges, and rinse water to reach every corner of the interior, which is essential for reusable or refillable jar programs.
• Improved Visibility: Consumers can see the product clearly before and during use, which builds trust and reduces the perception of hidden product residue at the bottom.

The lid design that pairs with a wide-mouth jar is equally important. Most 110ml wide-mouth PP jars come with a matching screw-on lid, which may include an inner liner or foam seal to protect contents from moisture and air exposure. Some versions offer child-resistant caps for pharmaceutical applications, while others use smooth overcaps designed for luxury cosmetic presentation.

Common Applications Across Industries

The 110ml wide-mouth PP jar's versatility makes it a go-to solution across multiple sectors. Below is a breakdown of the most common use cases:

Each of these industries has specific expectations when sourcing jars, which is why understanding the jar's technical specifications — not just its appearance — is essential before making a purchasing decision.

How to Evaluate Quality When Sourcing 110ml Wide-Mouth PP Jars

Not all PP jars are created equal. When comparing suppliers or evaluating product samples, buyers should examine several quality indicators to avoid costly mistakes down the line.

Wall Thickness and Structural Integrity

A well-manufactured 110ml PP jar should have uniform wall thickness throughout the body and base. Thin spots can crack under pressure or when dropped, while excessively thick walls add unnecessary weight and material cost. Ask suppliers for the gram weight of each jar — a standard 110ml wide-mouth PP jar typically weighs between 15g and 25g depending on intended use. Premium versions used in cosmetics often fall on the heavier end for a more substantial feel.

Lid Fit and Sealing Performance

The lid should thread smoothly without cross-threading risk and close securely without excessive torque. Request leak-proof testing data from the supplier, particularly if the jar will be shipped internationally or stored in humid environments. Some manufacturers offer induction sealing liners for airtight closure, which is a valuable feature for food and pharmaceutical applications.

Compliance and Certifications

For food and pharmaceutical use, verify that the PP resin used is food-grade and compliant with relevant regulations such as FDA 21 CFR (USA), EU Regulation No. 10/2011 (Europe), or GB standards (China). Request material safety data sheets (MSDS) and migration test reports where applicable. These documents are non-negotiable for import-export compliance in regulated industries.

Customization Options for Branding and Functionality

One of the major advantages of sourcing 110ml wide-mouth PP jars in bulk is the range of customization options available. Businesses can tailor jars to align with brand identity and product requirements without major tooling investment, especially when minimum order quantities are met.

• Color Options: PP can be compounded with masterbatch to produce virtually any color. Opaque white and black are most common in cosmetics; transparent or natural finishes are preferred in food and laboratory settings.
• Surface Printing: Screen printing, hot stamping, and offset printing can be applied directly to the jar body for logo or product information display without adhesive labels that may peel.
• Lid Styles: Options include flat screw caps, dome lids, flip-top caps, and child-resistant closures. Each serves a different functional or aesthetic purpose.
• Inner Liners: PE foam liners, aluminum foil liners, and pressure-sensitive liners can be added to enhance product protection and tamper evidence.
• Embossing and Debossing: For premium branding, logos and patterns can be molded directly into the jar surface during manufacturing.

Practical Tips for Storing and Handling PP Jars

Whether you're a manufacturer filling jars at scale or a consumer storing products at home, a few simple practices will extend the life and performance of your 110ml wide-mouth PP jars. Store empty jars away from direct sunlight and extreme temperatures, as prolonged UV exposure can cause some PP grades to become brittle over time. Avoid storing near strong solvents unless the jar has been specifically tested for solvent resistance beyond standard PP thresholds.

For filled jars, always close the lid securely after each use to prevent contamination and moisture ingress. If reusing jars, wash with warm soapy water and allow to dry fully before refilling — PP is dishwasher safe at moderate temperatures but should not be used in high-heat sterilization cycles unless rated for that purpose. Label all reused jars clearly, especially when storing chemicals or non-food items, to avoid accidental misuse.

Where to Buy and What to Expect in Terms of Pricing

110ml wide-mouth PP jars are available through plastic packaging manufacturers, wholesale distributors, and online marketplaces such as Alibaba, Made-in-China, and Amazon Business. Pricing varies significantly based on order volume, customization level, and quality grade. As a general guide, standard clear PP jars in bulk (5,000+ units) from Chinese manufacturers can range from $0.05 to $0.20 per unit, while premium cosmetic-grade versions with custom color and printing may reach $0.30 to $0.60 per unit or higher.

When sourcing internationally, factor in shipping costs, import duties, and lead times — typically 15 to 45 days for custom orders. Request physical samples before committing to a large order to verify quality, lid fit, and print accuracy. Reputable suppliers will readily provide samples and technical documentation. For smaller quantities, domestic distributors or packaging wholesalers offer faster delivery with less minimum order pressure, though at a higher per-unit cost.
