A Must-Read for Beginners: How to Choose Among 6 Types of Plastic Packaging? Everything You Need to Know.
A note to start:“”Hi, I’d like to order custom plastic packaging, but I don’t know which material to choose.””
This is a question our customer service team receives every day. Indeed, for those new to packaging procurement, terms like PET, PE and PP can easily leave you confused.
Don’t worry! In today’s article, we’ll useplain languageto explain the 6 most common plastic packaging types. After reading, you’ll be able to select like a pro!
First, remember this rule of thumb
Need transparency, go PET; need heat resistance, choose PP; want cheap, use PE; need rigidity, pick PVC
Of course, real-world selection is a bit more complex. Let’s go through them one by one.
1. PET: the most”photogenic” packaging material
Features:Transparent like glass, but it won’t shatter; rigid enough that you can’t squeeze it.
How to identify:Water bottles and cooking oil containers are mostly PET. Pick one up – the transparency is very high and the surface is hard.
What is it suitable for?
- Drinks and juice (need to show color)
- Cooking oil (needs oxygen barrier)
- Cosmetics (need a premium feel)
⚠️ Not recommended for:hot liquids (may deform above 70°C).
2. PE: the most”easygoing” material
PE comes in two types:
- HDPE (rigid PE):as hard as a shampoo bottle
- LDPE (soft PE):as soft as cling film
How to identify:Squeeze them: HDPE feels like a plastic sheet, LDPE like a plastic bag.
What is it suitable for?
- HDPE: shampoo, laundry detergent, milk bottles
- LDPE: cling film, shopping bags, tube packaging
Advantages:Safe and non-toxic, food-grade, and low cost.
3. PP: the only plastic that can go ”in the microwave” plastic
Features:Good heat resistance, withstands 121°C high-temperature sterilization.
How to identify:Microwave meal boxes and yogurt cups – the triangle mark at the bottom says”5″or”PP”。
What is it suitable for?
- Takeout meal boxes (need reheating)
- Hot-filled jams and sauces
- Pharmaceutical packaging (needs sterilization)
4. PVC: the value pick (but use with caution)
Features:Cheap, transparent, adjustable rigidity.
However:May contain plasticizers, not suitable for direct food contact.
What is it suitable for?
- Cosmetic bottles (no food contact)
- Plastic trays for electronics
- Shrink sleeve labels
⚠️ Not recommended:food packaging, especially oily foods.
5. PS: transparent but”brittle” packaging
Features:Highly transparent, but shatters when dropped.
How to identify:Disposable clear plastic boxes make a”crack” sound when snapped.
What is it suitable for?
- Fruit boxes at market stalls
- Disposable tableware
- Inner trays for electronics (no load-bearing needed)
Disadvantages:Not heat-resistant or impact-resistant, unsuitable for long-term packaging use.
6. PVDC: the luxury-grade”freshness king”
Features:Excellent barrier performance that keeps food fresh longer.
However:Expensive! Generally only for premium products.
What is it suitable for?
- Premium vacuum-packed cooked foods
- Pharmaceutical blister packaging
- imported cheese packaging
Quick selection reference table
To help you decide faster, we’ve put together a“3-second selection method”：
| Your need | Which material to choose | Reason |
|---|---|---|
| Want customers to see the product inside | PET | Highest transparency |
| Need microwave heating | PP | The only heat-resistant material |
| Control costs | PE / PVC | Affordable price |
| Food inside spoils easily | PVDC / PET | Good barrier performance |
| First-time purchase, want to play it safe | PE / PP | The safest choice |
A real customer case
Last month, an organic juice customer came to us saying their previous packaging always deformed and the juice oxidized and changed color easily.
After analyzing their product characteristics, we recommended switching toPET material + barrier layer laminated packaging. The results:
- No more packaging deformation (thanks to PET’s rigidity)
- Juice shelf life extended by 30% (the barrier layer prevents oxidation)
- Customer feedback”It looks more premium now” (improved transparency)
See,choosing the right material really solves problems!
Final words
Plastic packaging selection is as hard or as easy as you make it. The key isclarifying your needs first：
- What is my product?
- Does it need to be displayed?
- Does it need heat resistance?
- What’s the budget?
Answer these 4 questions, then compare with our introduction above, and you’ll basically know the answer.
