PP blister cup

PP Blister Cup Product Introduction

Product Overview

PP blister cups are disposable packaging containers made from polypropylene (PP) sheets through vacuum thermoforming. Using PP resin as the base material, toughening agents, brighteners, and other additives are blended, extruded, and calendared into sheets. These sheets are then formed into cup shapes via heat molding technology. Characterized by light weight, transparency, safety, and temperature resistance, PP blister cups are widely used in the food, beverage, and catering industries.

Product Performance

1.Physical Properties

● High-Temperature Resistance: Heat distortion temperature of approximately 65°C, suitable for short-term exposure to heat (e.g., hot beverages), but not recommended for long-term high-temperature use;

● Low-Temperature Resistance: Withstands -40°C freezing environments, ideal for ice cream, frozen food packaging, etc;

● Mechanical Strength: Density of ~0.91g/cm³, combining rigidity and flexibility for excellent folding resistance and durability;

● Transparency: High-clarity material allows clear visibility of contents, enhancing product appeal.

2.Safety Properties

● Non-Toxic & Harmless: Complies with food-contact standards (FDA, EU 10/2011, etc.), BPA-free, and safe for direct food contact;

● Barrier Properties: Provides moderate resistance to water vapor and oils, extending food shelf life.

3.Processing Properties

● High Moldability: Can be shaped into various forms (round, irregular shapes, etc.) via thermoforming to meet customized needs;

● Printing Compatibility: Supports silk screen, offset, hot stamping, and other surface treatments for brand enhancement.

Application Areas

● Food & Beverage: Bubble tea cups, juice cups, coffee cups, cold drink cups;

● Food Packaging: Disposable meal boxes, fruit trays, mooncake trays;

● Freezing & Preservation: Ice cream cups, dumpling boxes, glutinous rice ball containers;

● Industrial Use: Electronics trays, medical device packaging.

Product Features

Precautions

● Avoid High-Temperature Heating: Not microwave-safe or suitable for boiling water to prevent deformation or chemical release;

● Storage Conditions: Store in cool, dry environments away from direct sunlight to avoid aging and brittleness;

● Usage Scenarios: Recommended for cold and short-term warm beverages; opt for alternative materials (e.g., stainless steel) for prolonged high-temperature applications.
