The density is 500-800 gsm and can provide sufficient structural strength to withstand the pressure of full-load stacking.Purepack uses pure new material PP combined to produce 4mm correx sheets with high impact toughness in low-temperature environments. Each PP corrugated sheet has four-sided hot-melt edge sealing with a sealing layer thickness of 0.3-0.5mm, forming a sealing barrier at the cutting edge. Food-grade corrugated plastic boards have obtained certification from the FDA (USA) and SGS (EU).Choose The Perfect 4mm Corrugated Plastic Sheet4mm corrugated plastic sheet has many kinds of applications for you to choose.

Here are some of our cases:4mm Floor Protection SheetOur client is a home renovation company in the United States; each construction site requires large areas of floor protection materials. They previously used cardboard for floor protection, but the cardboard was not waterproof. Our 4mm corrugated plastic sheets help them solve the problem.Get instant QuoteSend Your Inquiry NowCorrugated plastic PackagingOur customer is a farm pack vegetables in cardboard boxes, but the boxes became damp and softened, causing the lower boxes to collapse when stacked, resulting in vegetable crushing and damage, with a loss rate of about 8%. Use a 4mm Correx turnover box instead; PP material is completely non-absorbent, and the cold storage environment does not affect the strength of the box. 4mm thickness has strong compressive strength and will not deform when stacked in 5 layers.Get instant QuoteSend Your Inquiry NowGet an Instant Quote Now Are You Ready to Customize Your 4mm Corrugated Plastic Sheet?Contact us to custom your 4mm corrugated plastic sheet solutions.

TestimonialsWe used to use cardboard boxes for shipping auto parts. The cardboard would get wet in the warehouse, and the boxes would collapse. We replaced Purepack\u2019s 4mm corrugated plastic boxes. They are waterproof, they stack without collapsing, and each box lasts about 50 trips. The corrugated plastic boxes have been used for 6 months.\u201d John MillerLogistics Manager, United States\u201cWe supply construction site hoardings to contractors in the Northeast US. We used to use plywood, but it was heavy, expensive, and would rot after a few months. We switched to Purepack\u2019s 4mm corrugated plastic sheets. They are light enough to install, strong enough to stand up in the wind, and they don\u2019t rot. A 4mm sheet lasts 2 years on a construction site. We now use 4mm sheets for all our hoarding needs.\u201d Dave Chen Operations Manager, AustraliaHow do we know if the edge sealing of 4 mm corrugated sheets is of good quality?There are three ways of determining the quality of edge banding:\u2460 Observation method \u2013 If the edge banding is not continuous and has an uneven width, this means that the edge banding is not uniform.\u2461 Press test \u2013 If there is any looseness or \u201cclicking\u201d sound made during the pressing process, this means that the edge is not tightly sealed.\u2462 Cross-section test \u2013 Get a part of the edge sealing and use a blade to get the cross-section of it. If the upper and lower edges are still separated after slicing, it means that the edge sealing is not properly done.What is the life span of 4mm cold chain turnover boxes?The life span of a 4mm cold chain turnover box made by 4mm correx sheets depends on the number of uses, type of cleaning, and storage temperatures. If normal use conditions where the turnover is once a day, and cleaning is done once a week, the life span of the box will be around 2-3 years at a temperature between -20\u00b0C and +40\u00b0C.What factors affect the life cycle of 4 mm Correx sheets?The three key factors that determine life:\u2460 Cleaning temperature \u2013 we suggest you use warm water below 40 \u00b0 C for cleaning. Water temperature exceeding 60 \u00b0 C can accelerate the aging of PP materials;\u2461 Disinfectant choice \u2013 Chlorine-containing disinfectants (such as sodium hypochlorite) can make the surface of PP brittle after long-term contact. You\u2019d better use hydrogen peroxide or peracetic acid disinfectants;\u2462 The stacking method \u2013 When you store empty boxes, it\u2019s better to store them upside down or folded; avoid long-term compression on one side, bacause it may cause deformation of the bottom layer.Let's Discuss Your Needs and Find the Right Solution!If you do not know how to choose the best solutions for your project, we are happy to discuss with you and offer suggestions.Send Your Inquiry Now Scroll to Top WechatWhatsapp+8615898740625Call Now+0018058073459Email NowEmail Now 4mm-Corrugated-Plastic-Sheet 4mm Corrugated Plastic Sheet Corrugated-Plastic-Box-for-Fruits Corrugated Plastic Box for Seafood and Frozen Meat ESD corrugated plastic box Corrugated plastic shipping boxes Chemical & Corrosion Resistant Reusable-Recyclable Longer service life with good edge banding technique Cold chain specific formula, normal use will not crack 1-about purepack About-Purepack 4mm Floor Protection Sheet Corrugated Plastic Packaging Are You Ready to Customize Your Perfect PP Sheet Solution Customer Gallery -Customer Gallery Quality Certification wechat\n<\/p>\n","protected":false},"excerpt":{"rendered":"
