High Temperature Cooking Resistant Packaging: 121℃ High Temperature Cooking Aluminium Plastic Bags | Pet Food High Temperature Sterilisation Packaging

Product Features

The design logic of high-temperature cooking-resistant packaging must revolve around five core requirements: barrier properties, heat sealability, mechanical strength, environmental friendliness, and cost control. Below are common material structure combinations and their functional characteristics based on these requirements:

---

1. Barrier Properties

Aluminum Foil Substrate (AL):
Aluminum foil provides excellent oxygen, water vapor, and light barrier properties, commonly used in high-demand scenarios (e.g., meat, ready-to-eat foods).
Typical Structures:

o PET/AL/CPP:
Outer PET (polyester) provides mechanical strength, middle AL for barrier properties, and inner CPP (cast polypropylene) enables heat sealing.

o PA/AL/CPP:
Nylon (PA) enhances puncture resistance, AL for barrier properties, and CPP for heat sealing.

High-Barrier Polymers:
Materials like EVOH (ethylene vinyl alcohol copolymer) and PVDC (polyvinylidene chloride) can replace aluminum foil for transparent packaging.
Structure Examples:

o PET/EVOH/CPP:
Transparent and highly barriered, suitable for foods requiring visibility.

---

2. Heat Sealability

· CPP or HDPE Inner Layer:
CPP (cast polypropylene) withstands high-temperature cooking (121–135°C) and has stable heat seal performance; HDPE (high-density polyethylene) is lower in cost but has slightly lower temperature resistance.

o PET/PA/CPP:
Transparent structure with CPP inner layer ensuring heat seal strength.

o PET/AL/HDPE:
Cost-effective combination suitable for short-term high-temperature sterilization.

3. Mechanical Strength

· Nylon (PA) or Polyester (PET) Outer Layer:
PA resists puncture, while PET resists stretching, enhancing the packaging's impact resistance.

o PA/AL/CPP:
Suitable for bone-in foods to prevent piercing damage.

o PET/PA/AL/CPP:
Four-layer structure offering a balance of strength and barrier properties, used for high-end food or pharmaceutical packaging.

---

4. Environmental Friendliness

Biodegradable Materials:
Materials like PLA (polylactic acid) and PBAT (polybutylene adipate-co-terephthalate) are used in environmentally friendly applications.

o PLA/EVOH/CPP:
High biodegradability, but requires optimization for temperature resistance.

Recyclable Polyolefins:
Single-material PP or PE composite films simplify recycling processes.

---

5. Cost Control

· Simplified Structures:
Replace aluminum foil layers with bilayer composites (e.g., BOPA/CPP) to reduce material costs.

· Recycled Material Application:
Use recycled aluminum foil or plastic substrates to lower raw material costs.

II. Demand Translation Based on QFD Model

Through Quality Function Deployment (QFD), user requirements are translated into quantifiable technical indicators:

User Requirement	Technical Indicator	Test Method/Standard
High Barrier Properties	Oxygen Transmission Rate ≤0.5 cc/m²·day	GB/T 1038 (Differential Pressure Method)
	Water Vapor Transmission Rate ≤0.5 g/m²·day	GB/T 16928 (Cup Method)
Heat Seal Strength	Heat Seal Strength ≥45 N/15mm	GB/T 2358 (Heat Seal Tester)
Mechanical Strength	Drop Test (no breakage from 1m height)	GB/T 4857 (Simulated Transport Drop Test)
	Compression Strength ≥400N	Static Load Test
Environmental Friendliness	Extractables ≤10 mg/m²	GB 31604 (Migration Test for Food Contact Materials)

III. Application Scenarios and Market Positioning

1. Market Positioning

High-End Food Packaging:
Targeted at pre-made dishes and ready-to-eat meats (e.g., Buddha Jumps Over the Wall, cured meats), using PET/AL/CPP or PA/AL/CPP structures, emphasizing long shelf life (1–2 years) and high barrier properties.

Pharmaceuticals and Nutritional Products:
Used for medical nutritional meals and infant complementary foods, requiring extractables and migration testing, primarily using PET/PA/AL/CPP structures.

Environmental Niche Market:
Promotes PLA/EVOH composite films to attract green consumers, suitable for organic foods or products exported to the EU.

2. Product Portfolio Strategy

Basic Models:
BOPA/CPP bilayer structure, low cost, suitable for ambient-temperature, short-shelf-life foods (e.g., soy products).

High-Performance Models:
Four-layer PET/PA/AL/CPP, resistant to 135°C high temperatures, used for pet food and military ready-to-eat meals.

Customized Models:
Adds features like easy-tear openings and stand-up bottoms to enhance user experience, suitable for takeout soup products.

3. Scenario Expansion

Home and Outdoor Use:
Drop-resistant design (1m drop resistance) suitable for travel picnics, packaging instant porridge or frozen foods.

Industrial Applications:
Moisture-proof packaging for chemical reagents using AL-based barrier layers, offering corrosion resistance and strong sealing.
