Product Overview – PP Compartment Tray Designed for Industrial Pastry Production

This PP compartment tray for industrial pastry production is specially designed for food processing factories that require standardized, efficient, and reliable handling of individually portioned baked goods.
The tray features 20 round individual cavities, each engineered to hold a single pastry piece, ensuring clear separation throughout production, freezing, storage, and internal logistics.

Unlike general-purpose food trays, this industrial PP pastry tray is developed for high-volume, repeatable manufacturing environments, where product consistency, freezing performance, and handling efficiency are critical.
It is widely used in centralized pastry factories producing traditional and modern pastries such as individually shaped baked products, pre-baked items, and frozen dough-based snacks.

With an overall size of 395 × 296 × 10 mm and 70 mm diameter round cavities, this tray provides a balance between compact footprint and optimal cavity spacing, making it suitable for stacking, conveying, and freezing operations.

Typical Application Scenarios in Industrial Food Processing

This PP compartment food processing tray is suitable for a wide range of industrial production scenarios, including:

• Industrial pastry factories
  Used for mass production of individually portioned pastries requiring separation before freezing.

• Central kitchens & commissary kitchens
  Ideal for standardized production and temporary storage of pre-formed bakery items.

• Frozen food manufacturing facilities
  Designed to withstand rapid freezing and low-temperature storage without deformation.

• Bakery chains with centralized production lines
  Supports consistent product sizing and streamlined logistics.

The tray is commonly used for round-shaped pastries, including traditional filled pastries such as wife cakes, as well as other baked or semi-baked products that require individual positioning to prevent sticking or deformation.

Tray Structure & 20-Cavity Compartment Design Explained

The 20-cavity compartment design is not accidental; it is optimized for industrial efficiency.

Each cavity is circular with a diameter of 70 mm, which matches common pastry dimensions used in large-scale production. The round cavity geometry provides:

• Even support for soft or semi-rigid pastry bases

• Reduced stress points compared to square cavities

• Better shape retention during freezing and handling

The separation between cavities ensures that each pastry remains independent, avoiding contact during freezing—a key factor in preventing surface adhesion and product damage.

The shallow yet stable tray profile allows for easy stacking, helping factories maximize freezer space while maintaining airflow around products.

Material Advantage – Food Grade PP for Food Processing Trays

Polypropylene (PP) is one of the most widely accepted materials for food processing trays, and for good reason.

This PP compartment tray is manufactured using food-grade PP sheet, offering:

• Excellent chemical stability

• Odorless and non-toxic material properties

• Safe for direct food contact

• Resistance to oils, fats, and sugar residues

Compared to alternative plastics, PP provides superior performance in low-temperature environments, making it especially suitable for frozen food applications.

---

Low Temperature Resistance & Freezing Performance (-45℃)

A key advantage of this freezer-safe PP tray is its ability to withstand temperatures as low as -45℃.

In industrial frozen food production, trays are often exposed to:

• Rapid blast freezing

• Extended frozen storage

• Frequent temperature fluctuations

The PP sheet used in this tray maintains its structural integrity under these conditions. It does not become brittle, crack, or deform when subjected to low temperatures.

This makes the tray suitable for:

• Pre-freezing pastry products

• Frozen storage prior to packaging

• Handling frozen items without breakage

Stable cavity shape ensures that each pastry retains its intended form even after freezing and thawing cycles.

---

Anti-Sticking Performance & Product Separation Benefits

One of the biggest challenges in frozen pastry production is product sticking.

When pastries touch each other during freezing, surface moisture and sugar content can cause them to adhere, leading to:

• Product damage during separation

• Inconsistent appearance

• Increased waste

The individual compartment design of this PP tray eliminates direct contact between pastries, significantly reducing sticking issues. Each cavity holds a single unit, allowing air to circulate evenly and freeze products uniformly.

As a result, factories benefit from:

• Cleaner demolding

• Improved product presentation

• Reduced handling time

---

Compatibility with Automated and Semi-Automated Production Lines

This industrial PP compartment tray is designed with automation compatibility in mind.

Its consistent dimensions and stable structure allow it to be easily integrated into:

• Manual loading lines

• Semi-automated placing systems

• Conveyor-based workflows

The tray’s rigidity supports repeated handling without warping, ensuring reliable movement through production stages. This helps reduce labor dependency and improves overall throughput.

---

Efficiency Improvement for Large-Scale Pastry Production

Using a dedicated PP pastry production tray helps manufacturers optimize efficiency across multiple stages:

• Faster loading and unloading

• Reduced product loss

• Improved freezer space utilization

• Standardized batch handling

By maintaining consistent product positioning, the tray supports predictable freezing and storage outcomes, which is essential for large-scale operations.

---

Durability, Reusability & Handling Performance

This PP food processing tray is designed for durability in factory environments.

Key durability features include:

• Resistance to bending during handling

• Stable shape under stacking pressure

• Long service life under repeated use

Its reusable nature makes it suitable for internal circulation within factories, reducing the need for frequent replacement.

---

Customization Options for Industrial Buyers

To meet diverse production needs, customization is available for this PP compartment tray, including:

• Different cavity diameters

• Customized cavity counts

• Thickness adjustment

• Tray color options

• Logo or identification marking

Customization allows manufacturers to adapt the tray precisely to their product specifications and production workflows.

---

Quality Control & Manufacturing Capability

The tray is produced using controlled thermoforming processes to ensure:

• Uniform cavity depth

• Consistent wall thickness

• Smooth, clean edges suitable for food contact

Strict quality control helps maintain reliable performance across large production volumes.

---

Sustainability & Responsible Material Choice

While designed for industrial use, this PP tray for food processing also supports responsible material use:

• PP is recyclable in many regions

• Long service life reduces material consumption

• Improved separation reduces food waste

Efficient design contributes to more sustainable production practices.
