Blister Packaging PP Rigid Sheet

Plastic China New Material (Zibo) Co., Ltd. is one of the most reliable manufacturers and suppliers of blister packaging pp rigid sheet in China. With abundant experience, we warmly welcome you to buy high quality blister packaging pp rigid sheet from our factory. Contact us for more details.

Blister packaging PP rigid sheet is dedicated food-grade polypropylene blister material manufactured via stable precision extrusion. It delivers uniform thickness from 0.18mm to 1.50mm and smooth defect-free surface for small blister automatic forming equipment.

Unlike non-microwavable PET and PS sheets, this PP sheet withstands repeated microwave heating and long-term -18℃ frozen circulation without cracking or swelling. Stable softening property and ultra-low shrinkage rate reproduce delicate blister mold details, ideal for mass production of disposable food blister boxes, cup lids and mini electronic storage trays.

1.Food-Grade Clear Base For Premium Display

Made of high-purity virgin PP resin with ultra-low haze, the sheet fully restores food color and printing ink brightness. Custom tinted colors are supported to match personalized packaging brand demands.

2.Stable Thermoforming For Small Blister Equipment

Uniform thermal softening and low forming shrinkage avoid cracking, whitening and deformation during shallow & medium-depth blister drawing, perfectly matching small automatic blister machines for mass disposable packaging. Consistent thickness cuts raw material waste and reject rates.

3.Unique Microwave & Freeze Resistance

Safe for repeated microwave reheating without harmful substance precipitation; no brittleness or swelling under long-term -18℃ frozen storage and high-oil sauce contact - unmatched advantage over PET, APET and ordinary PS sheets.

4.Eco-Friendly Fully Recyclable Material

Single-component polypropylene without plasticizers complies with FDA and EU food contact standards, fully recyclable to meet global green packaging regulations.

Customers who purchase PP products may be concerned about the issue of the sheet becoming brittle after freezing.

 

1. Low-Temperature Resistant Customized PP Formula to Prevent Cold Brittleness

We solve customers' core concern that PP sheets turn brittle under freezing conditions. Ordinary general PP resin suffers severely reduced molecular flexibility at low temperatures, leading to cracking, chipping and whitening when frozen. We adopt special low-temperature toughened virgin PP raw materials with optimized molecular ductility modifiers. The customized formula retains excellent flexibility and impact resistance even in cold storage environments, effectively avoiding brittle fracture of blister boxes after freezing.

2. Special Low-Temperature Freezing Simulation Test Before Delivery

We add exclusive cold resistance testing items for every batch of PP rigid sheets. QC teams conduct professional low-temperature freezing simulation tests to replicate customers' cold storage scenarios. After long-time freezing treatment, we test bending resistance, impact strength and edge toughness of molded blister products. Any sheets showing brittle cracking under low temperature are eliminated strictly, ensuring stable anti-brittle performance in cold environments.

3. Complete Technical Guidance & After-Sales Remake Service

If your blister boxes made from our PP sheets become brittle after freezing, our professional technical team will provide targeted forming and storage parameter suggestions to improve product performance. For batches with unqualified low-temperature toughness caused by our production, we offer free remake and reship service to completely eliminate your worries about cold brittleness losses.
