PP sheets for cheese stick packaging

Brif Intro

When PP (polypropylene) sheets are used for cheese stick packaging, thermoforming blister process is usually used to make the packaging.

Advantages and characteristics of PP sheets

Food safety:

Non-toxic and harmless: PP is a safe and non-toxic material that complies with relevant regulations and standards for food contact materials, such as FDA and EU food contact material regulations.

No odor: PP material itself has no odor and will not affect the flavor of cheese sticks.

Good mechanical properties:

High strength and toughness: PP sheets have good impact resistance and toughness, which can protect cheese sticks from damage during transportation and storage.

Abrasion resistance and tear resistance: PP sheets have high abrasion resistance and tear resistance, ensuring the durability of the packaging.

Excellent barrier properties:

Moisture barrier properties: PP sheets can effectively block moisture, preventing cheese sticks from losing moisture or absorbing external moisture during storage.

Moderate oxygen barrier properties: PP sheets have a certain oxygen barrier capacity, which can extend the shelf life of cheese sticks.

Thermoforming performance:

Easy to thermoform: PP sheets have good plasticity during the thermoforming process, and can produce complex shapes and details such as containers and lids.

Low density: PP materials are lighter, which helps reduce the total weight of the packaging and transportation costs.

Good transparency:

High transparency: Transparent PP sheets can show the appearance of cheese sticks and improve the shelf appeal of the product.

Gloss: PP sheets have high gloss, which enhances the aesthetics of the packaging.

Environmental characteristics:

Recyclability: PP materials are fully recyclable, which helps reduce environmental pollution.

Low carbon footprint: PP production and recycling processes have relatively low energy consumption, which helps reduce carbon footprint.

Corona treatment of PP sheets

PP sheets used as cheese stick packaging also need to be corona treated, so that product information and patterns can be printed on the packaging.

Surface corona treatment is a common surface treatment method that is widely used in various plastic sheets. PP plastic sheets themselves have many excellent properties, but their surface energy is low and their surface wettability is poor, which affects their adhesion to materials such as inks and glues. Through corona treatment, the surface energy of PP sheets can be increased, thereby improving their printing, coating and bonding properties.

Improving surface polarity: Corona treatment can increase the polarity of the surface of PP sheets, making them easier to be wetted by water-based inks, coatings and adhesives, thereby improving bonding strength.

Improving printing performance: Corona treatment can improve the printing suitability of the surface of PP sheets and reduce printing defects such as bubbles, pinholes, uneven ink paths, etc.

Enhancing composite performance: Corona treatment can improve the bonding strength of PP sheets with other materials, thereby improving the performance of composite materials.

Production process of PP sheets

The production process of PP plastic sheet mainly includes the following steps:

• Raw material preparation: Mix and stir PP resin, additives and other raw materials.
• Melting: Send the raw material mixture into the melting machine for melting.
• Extrusion: Extrude the molten PP material into a film through an extruder.
• Cooling: Cool and shape the extruded film.
• Winding: Wind the cooled and shaped film into a coil.
